  • Javascript API not working for Chrome or Safari on JW Player 5.9

    - by Lando
    I am working on a custom interface for the JW Player which displays the current track title and has play/pause, next track, previous track and volume toggle buttons. It works for IE8/9 and FF but fails for Chrome and Safari. Chrome's console gives the following error: Uncaught TypeError: Object # has no method 'addControllerListener' This is the code I am using for testing. <div id="container">Loading the player ...</div> <script type="text/javascript"> jwplayer("container").setup({ image: "preview.jpg", height: 320, width: 480, modes: [ { type: "html5" }, { type: "flash", src: "player.swf" } ], 'playlist': [ { 'file': "audio/01.mp3", 'title': "Track 1" }, { 'file': "audio/02.mp3", 'title': "Track 2" }, { 'file': "audio/03.mp3", 'title': "Track 3" } ], }); function playerReady(obj) { player = document.getElementById(obj.id); displayFirstItem(); }; function displayFirstItem() { try { playlist = player.getPlaylist(); } catch(e) { setTimeout("displayFirstItem()", 100); } player.addControllerListener('ITEM', 'itemMonitor'); itemMonitor({index:0}); }; function itemMonitor(obj) { $('#nowplaying').html('<span><strong>Now Playing:</strong> ' + playlist[obj.index]['title'] + '</span>'); }; </script> <div id="nowplaying"></div> <div class="control_bar"> <ul> <li onclick='player.sendEvent("play");'>[ &#8250; ] Play / Pause</li> <li onclick='player.sendEvent("prev");'>[ &laquo; ] Previous item</li> <li onclick='player.sendEvent("next");'>[ &raquo; ] Next item</li> </ul> </div> I have searched and tried several modifications, like adding the javascriptid parameter, nothing seems to work for Chrome or Safari. Any ideas? Thanks

  • Footer positioning with CSS and 960gs

    - by Nick
    I'm new to doing layouts with CSS (I haven't done any web design for a long long time) and I can't seem to figure out how to get the footer of the page to display at the bottom the way I want. Requirements: -Display at bottom of content if content exceeds vertical size of viewport -Display at bottom of viewport if viewport exceeds vertical size of content. The code that I am using sets the footer at the bottom of the viewport, but if I size the browser to be shorter than the content, it just covers the content. Code: <div style="background-image:url(footer_bg.jpg); background-position:bottom; background-repeat:repeat-x; height:235px; width:100%; bottom:0px; position:absolute;"></div> My main goal is to have a footer with text (ie. company info, contact info) and a background gradient. I'd like the footer background to span the width of the page, but I don't know if I can do that with the 960 gs divs.

  • How can i zip files in Java and not include files paths

    - by Ignacio
    For example, i want to zip a file stored in /Users/me/Desktop/image.jpg I maded this method: public static Boolean generateZipFile(ArrayList<String> sourcesFilenames, String destinationDir, String zipFilename){ // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // VER SI HAY QUE CREAR EL ROOT PATH boolean result = (new File(destinationDir)).mkdirs(); String zipFullFilename = destinationDir + "/" + zipFilename ; System.out.println(result); // Create the ZIP file ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFullFilename)); // Compress the files for (String filename: sourcesFilenames) { FileInputStream in = new FileInputStream(filename); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filename)); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); return true; } catch (IOException e) { return false; } } But when i extract the file, the unzipped files have the full path. I don't want the full path of each file in the zip i only want the filename. How can i made this?

  • After drawing circles on C# form how can i know on what circle i clicked?

    - by SorinA.
    I have to represent graphically an oriented graph like in the image below. i have a C# form, when i click with the mouse on it i have to draw a node. If i click somewhere on the form where is not already a node drawn it means i cliked with the intetion of drawing a node, if it is a node there i must select it and memorize it. On the next mouse click if i touch a place where there is not already a node drawn it means like before that i want to draw a new node, if it is a node where i clicked i need to draw the line from the first memorized node to the selected one and add road cost details. i know how to draw the circles that represent the nodes of the graph when i click on the form. i'm using the following code: namespace RepGraficaAUnuiGraf { public partial class Form1 : Form { Graphics graphDrawingArea; Bitmap bmpDrawingArea; Graphics graph; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graph = Graphics.FromHwnd(this.Handle); } private void Form1_Click(object sender, EventArgs e) { DrawCentralCircle(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y, 15); graph.DrawImage(bmpDrawingArea, 0, 0); } void DrawCentralCircle(int CenterX, int CenterY, int Radius) { int start = CenterX - Radius; int end = CenterY - Radius; int diam = Radius * 2; bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graphDrawingArea.DrawEllipse(new Pen(Color.Blue), start, end, diam, diam); graphDrawingArea.DrawString("1", new Font("Tahoma", 13), Brushes.Black, new PointF(CenterX - 8, CenterY - 10)); } } } My question is how can i find out if at the coordinates (x,y) on my form i drew a node and which one is it? I thought of representing the nodes as buttons, having a tag or something similar as the node number(which in drawing should be 1 for Santa Barbara, 2 for Barstow etc.)

  • Binding DataTemplates (or another aproach)

    - by Bataglião
    Hi all, I'm having some troubles trying to dynamically generate content in WPF and after it bind data. I have the following scenario: TabControl - Dynamically generated TabItems through DataTemplate - inside TabItems, I have dynamic content generated by DataTemplate that I wish to bind (ListBox). The code follows: ::TabControl <TabControl Height="252" HorizontalAlignment="Left" Name="tabControl1" VerticalAlignment="Top" Width="458" Margin="12,12,12,12" ContentTemplate="{StaticResource tabItemContent}"></TabControl> ::The Template for TabControl to generate TabItems <DataTemplate x:Key="tabItemContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <ListBox ItemTemplate="{StaticResource listBoxContent}" ItemsSource="{Binding}"> </ListBox> </Grid> </DataTemplate> ::The template for ListBox Inside each TabItem <DataTemplate x:Key="listBoxContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="22"/> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Image Grid.Column="0" Source="{Binding Path=PluginIcon}" /> <TextBlock Grid.Column="1" Text="{Binding Path=Text}" /> </Grid> </DataTemplate> So, when I try to do this on code inside a loop to create the tabitems: TabItem tabitem = tabControl1.Items[catIndex] as TabItem; tabitem.DataContext = plugins.ToList(); where 'plugins' is an Enumerable The ListBox is not bounded. I tried also to find the ListBox inside the TabItem to set the ItemSource property but no success at all. Someone have an idea on how to do that? Thanks in advance.

  • Python print statement prints nothing with a carriage return

    - by Jonathan Sternberg
    I'm trying to write a simple tool that reads files from disc, does some image processing, and returns the result of the algorithm. Since the program can sometimes take awhile, I like to have a progress bar so I know where it is in the program. And since I don't like to clutter up my command line and I'm on a Unix platform, I wanted to use the '\r' character to print the progress bar on only one line. But when I have this code here, it prints nothing. # Files is a list with the filenames for i, f in enumerate(files): print '\r%d / %d' % (i, len(files)), # Code that takes a long time I have also tried: print '\r', i, '/', len(files), Now just to make sure this worked in python, I tried this: heartbeat = 1 while True: print '\rHello, world', heartbeat, heartbeat += 1 This code works perfectly. What's going on? My understanding of carriage returns on Linux was that it would just move the line feed character to the beginning and then I could overwrite old text that was written previously, as long as I don't print a newline anywhere. This doesn't seem to be happening though. Also, is there a better way to display a progress bar in a command line than what I'm current trying to do?

  • Im Stumped, Why is UIImage\Texture2d memory not being freed

    - by howsyourface
    I've been looking everywhere trying to find a solution to this problem. Nothing seems to help. I've set up this basic test to try to find the cause of why my memory wasn't being freed up: if (texture != nil) { [texture release]; texture = nil; } else { UIImage* ui = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image" ofType:@"png"]]; texture = [[Texture2D alloc] initWithImage:ui]; } Now i would place this in the touches began and test by monitoring the memory usage using intstruments at the start (normally 11.5 - 12mb) after the first touch, with no object existing the texture is created and memory jumps to 13.5 - 14 However, after the second touch the memory does decrease, but only to around 12.5 - 13. There is a noticeable chunk of memory still occupied. I tested this on a much larger scale, loading 10 of these large textures at a time The memory jumps to over 30 mb and remains there, but on the second touch after releasing the textures it only falls to around 22mb. I tried the test another time loading the images in with [uiimage imagenamed:] but because of the caching this method performs it just means that the full 30mb remains in memory.

  • Eclipse and JavaFX? is it just me?

    - by jeff porter
    I'm looking at learning JavaFX. I've tried setting Eclipse to develop a small app and I've downloaded the Eclipse plugin. Eclipse JavaFX plugin BUT... it just seems, well, flakey. So I have 3 questions... 1: Is there a better plugin? 2: Or is there some great set of tutorials out there that I'm missing? 3: finally, is it meant to be easy to call Java code from FX? I'm stuggling, it there a good example somewhere? On questions 1 & 2, Eclipse underlines code in red that just shouln't be. For example.. see this image... Why does it underline bit of imports in red? I know this is little of an open ended question. So I guess my main question is this... Is my experiance of JavaFX and Eclipse the best I can hope for? Or am I missing something ? (and I'm not looking for a Yes/No response) :-) Just looking for a discussion on how best to learn/develop JavaFx.

  • How do display a UserControl with satisfying all imports

    - by Yost
    Dear SO, I'm having some issues with Silverlight 4/ MEF. I have a basic framework setup with a Silverlight Navigation app at the core. Image link to the diagram for clarification The main app (Desu) contains some pages and controls that export en import nicely. I dynamicly load controls from Desu.Controls(like an imageviewer which i identify with the IImageViewer interface) and some pages from Desu.Pages. The first problem I had was with dynamicly loading pages and being able to navigate to these pages (eg. use dummyhttp://blagh/desutestpage.aspx#/Activation when Desu.Pages was loaded from the xap). I solved this by using a custom MetaAttribute and a custom contentloader. Now for the question part: I want to load the ImageViewerControl from Desu.Controls in HomePage in Desu. I haven't loaded the Desu.Controls into the package though. When i try to load the control it gives me CompositionException because it can't satisfy the ImageViewControl import. I tried setting AllowRecomposition=true but that didn't help. So is it possible to load a control without satisfying all imports and, if yes, how does one do this?

  • Loading Facebook fb:profile-pic via AJAX in Facebook Connect site

    - by mbrevoort
    After a page loads, I'm making an AJAX request to pull down an HTML chunk that contains tags representing a Facebook user profile picture. I append the result to a point in the DOM but the logos don't load, instead all I see is the default silhouette. Here's simply how I'm loading the HTML chunk with jQuery $.ajax({ url: "/facebookprofiles" success: function(result) { $('#profiles').append(result); } }); The HTML that I'm appending is a list of diffs like this: <div class="status Accepted"> <fb:profile-pic class="image" facebook-logo="true" linked="true" size="square" uid="1796055648"></fb:profile-pic> <p> <strong>Corona Kingsly</strong>My Status Update<br/> <span style="font-size: 0.8em">52 minutes ago</span> </p> </div> Any ideas? I assume the fb tags are not being processed once the dom is loaded. Is there any way to make that happen? I'm not seeing any exceptions or errors in my Firebug console. Thanks

  • Jquery Using Jeditable and activating on click

    - by BandonRandon
    I found this to be almost exactly what I'm trying to do. I'm using Jeditable I can get the default setup to work. I've also been able to get the code in the forum above to work. I believe my problem is that because I'm using a table I need to so something else to select the previous element. Here is my HTML <table> <tr> <td width="5%"><input class="cat_checkbox" type="checkbox" name='delete_cat[]' value='<?php echo("$cat_data[cat_id]");?>' /></td> <td width="90%" class="edit_cat_title" id='unique_id'>Category</td> <td width="5%"><a href="#" class="edit_cat_title_trigger"><img src="images/edit.gif" border="0"></a></td> </tr> </table> and here is my JQuery: //modify title content on the fly $('.edit_cat_title').editable('action.php', { name : 'cat_title', indicator : 'Saving...', submit : 'OK', cancel : 'Cancel', tooltip:'click to edit', event : 'edit' }); //trigger with the click of the edit image $(".edit_cat_title_trigger").bind("click", function() { $(this).prev().trigger("edit_cat_title"); }); I know I probably should be able to figure it out and I know all i have to do is change $(this).prev().trigger("edit_cat_title"); to the right thing but I'm still really new to Jquery. Thanks

  • Is it possible to write map/reduce jobs for Amazon Elastic MapReduce using .NET?

    - by Chris
    Is it possible to write map/reduce jobs for Amazon Elastic MapReduce (http://aws.amazon.com/elasticmapreduce/) using .NET languages? In particular I would like to use C#. Preliminary research suggests not. The above URL's marketing text suggests you have a "choice of Java, Ruby, Perl, Python, PHP, R, or C++", without mentioning .NET languages. This Amazon thread (http://developer.amazonwebservices.com/connect/thread.jspa?messageID=136051 -- "Support for C# / F# map/reducers") explicitly says that "currently Amazon Elastic MapReduce does not support Mono platform or languages such as C# or F#." The above suggests that it can't be done. I'm wondering if there are any workarounds, though. For example, can I modify the Elastic MapReduce machine image for my account, and install Mono on there? An alternative, suggested by Amazon FAQs "Using Other Software Required by Your Jar" (http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/index.html?CHAP_AdvancedTopics.html) and "How to Use Additional Files and Libraries With the Mapper or Reducer" (http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/index.html?addl_files.html), is to make the first step of the Map/Reduce job be to install Mono on the local instance. That sounds kind of inefficient, but maybe it could work? Maybe a saner alternative would be to try to forgo the convenience of Elastic MapReduce, and manually set up my own Hadoop cluster on EC2. Then I assume I could install Mono without difficulty.

  • How to adjust size of programatically created Bitmap to match text drawn on it?

    - by TooFat
    I have the following .ashx page that takes some query string parameters and returns a bitmap with the specified text written on it. The problem I have is that I am currently just manually setting the initial size of the bitmap at 100 X 100 when what I really want is to have the bitmap be just big enough to include all the text that was written to it. How can I do this? public void ProcessRequest (HttpContext context) { context.Response.ContentType = "image/png"; string text = context.Request.QueryString["Text"]; //set FontName string fontName; if (context.Request.QueryString["FontName"] != null) { fontName = context.Request.QueryString["FontName"]; } else { fontName = "Arial"; } //Set FontSize int fontEms; if (context.Request.QueryString["FontSize"] != null) { string fontSize = context.Request.QueryString["FontSize"]; fontEms = Int32.Parse(fontSize); } else { fontEms = 12; } //Set Font Color System.Drawing.Color color; if (context.Request.QueryString["FontColor"] != null) { string fontColor = context.Request.QueryString["FontColor"]; color = System.Drawing.ColorTranslator.FromHtml(fontColor); context.Response.Write(color.ToString()); } else { color = System.Drawing.Color.Red; } using (System.Drawing.Text.PrivateFontCollection fnts = new System.Drawing.Text.PrivateFontCollection()) using (System.Drawing.FontFamily fntfam = new System.Drawing.FontFamily(fontName)) using (System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(color)) using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100)) { using (System.Drawing.Font fnt = new System.Drawing.Font(fntfam, fontEms)) { fnts.AddFontFile(System.IO.Path.Combine(@"C:\Development\Fonts\", fontName)); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, fnt, brush, new System.Drawing.Point(0, 0)); string imgPath = System.IO.Path.Combine(@"C:\Development\MyPath\Images\Text", System.IO.Path.GetRandomFileName()); bmp.Save(imgPath); context.Response.WriteFile(imgPath); } } }

  • Preventing a button from responding to 'Enter' in ASP.net

    - by kd7iwp
    I have a master template that all the pages on my site use. In the template there is an empty panel. In the code-behind for the page an imagebutton is created in the panel dynamically in my Page_Load section (makes a call to the DB to determine which button should appear via my controller). On some pages that use this template and have forms on them, pressing the Enter key fires the click event on this imagebutton rather than the submit button in the form. Is there a simple way to prevent the imagebutton click event from firing unless it's clicked by the mouse? I'm thinking a javascript method is a hack, especially since the button doesn't even exist in the master template until the button is dynamically created on Page_Load (this is ugly since I can't simply do <% =btnName.ClientId %> to refer to the button's name in my aspx page). I tried setting a super-high tabindex for the image button and that did nothing. Also set the button to be the DefaultButton in its panel on the master template but that did not work either.

  • curios about CCSpriteBatchNode's addchild method

    when diving into "learn cocos2d game development with ios5", in ch08 in EnemyCache.m -(id) init { if ((self = [super init])) { // get any image from the Texture Atlas we're using CCSpriteFrame* frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"monster-a.png"]; batch = [CCSpriteBatchNode batchNodeWithTexture:frame.texture]; [self addChild:batch]; [self initEnemies]; [self scheduleUpdate]; } return self; } so batch is with texture "monster-a.png" in EnemyEntity.m's initWithType method switch (type) { case EnemyTypeUFO: enemyFrameName = @"monster-a.png"; bulletFrameName = @"shot-a.png"; break; case EnemyTypeCruiser: enemyFrameName = @"monster-b.png"; bulletFrameName = @"shot-b.png"; shootFrequency = 1.0f; initialHitPoints = 3; break; case EnemyTypeBoss: enemyFrameName = @"monster-c.png"; bulletFrameName = @"shot-c.png"; shootFrequency = 2.0f; initialHitPoints = 15; break; default: [NSException exceptionWithName:@"EnemyEntity Exception" reason:@"unhandled enemy type" userInfo:nil]; } if ((self = [super initWithSpriteFrameName:enemyFrameName])) { //... } so the returned object may be in 3 different frame. since Only the CCSprites that are contained in that texture can be added to the CCSpriteBatchNode, obviously, 'monster-b.png' is not contained in 'monster-a.png', why the different enemy can still be added to the batch?

  • Fast, very lightweight algorithm for camera motion detection?

    - by Ertebolle
    I'm working on an augmented reality app for iPhone that involves a very processor-intensive object recognition algorithm (pushing the CPU at 100% it can get through maybe 5 frames per second), and in an effort to both save battery power and make the whole thing less "jittery" I'm trying to come up with a way to only run that object recognizer when the user is actually moving the camera around. My first thought was to simply use the iPhone's accelerometers / gyroscope, but in testing I found that very often people would move the iPhone at a consistent enough attitude and velocity that there wouldn't be any way to tell that it was still in motion. So that left the option of analyzing the actual video feed and detecting movement in that. I got OpenCV working and tried running their pyramidal Lucas-Kanade optical flow algorithm, which works well but seems to be almost as processor-intensive as my object recognizer - I can get it to an acceptable framerate if I lower the depth levels / downsample the image / track fewer points, but then accuracy suffers and it starts to miss some large movements and trigger on small hand-shaking-y ones. So my question is, is there another optical flow algorithm that's faster than Lucas-Kanade if I just want to detect the overall magnitude of camera movement? I don't need to track individual objects, I don't even need to know which direction the camera is moving, all I really need is a way to feed something two frames of video and have it tell me how far apart they are.

  • jQuery: Stop browser scrolling on event update beyond the fold?

    - by neezer
    I have several links at the bottom of my page that update content at the top of my page (more than a viewport away). Here's the gist of what the update looks like: $('#private-photo div').fadeOut(function() { $(this).html('<%= escape_javascript(image_tag current_user.private_photo.image.url(:profile)) %>'); }).fadeIn(); Basically it's just fading out the old content and fading in the new content. My problem is that when this happens, the browser window automatically scrolls up just far enough so that the bottom of the updated content (#private-photo div) appears at the top of the browser viewport. I do not want this to happen. I want the content to be updated (still fading in and out), but without the browser viewport realigning its focus. I want to keep the animation because if the user has a big enough screen, or if they are using a link closer to the top of the page, I still want them to see the animation. Any ideas about how to prevent the browser from scrolling as described? If not, any suggestions for workarounds? FYI, I have this same problem in Safari 4, Chrome (for Mac), & Firefox 3.5. EDIT: Here's the link that calls the update action, which is itself inside a Colorbox: $('a.edit-photo').colorbox({ title: function() { return 'Edit Photo in ' + $(this).attr('rel'); }, overlayClose: false, onComplete: function() { $('#edit-photo-modal').submit(function(e) { $('#photo_submit').after('<span id="saving">Saving...</span>'); e.preventDefault(); $.post($(this).attr('action'), $(this).serialize(), function() { $('#edit-photo-modal #saving').text('Saved!'); }, "script"); }); } }); The lightbox opens, presents a form fetched through an AJAX request, then (on submit) triggers the update action mentioned above. I had these links outside of the Colorbox in an earlier design revision, and they exhibited the same problem, so I've ruled out Colorbox itself as a cause. If you need anymore info, let me know!

  • JW Player playlist only loads randomly in IE, works fine in FF every time

    - by meow
    The playlist loads every time in FF but only the first time in IE (6-8), after that only randomly. If I alert the error that's thrown I get "TypeError: playerReady is undefined". My code looks good and obviously works since FF displays the playlist perfectly. I've got no idea how to solve this. Anyone? <script type='text/javascript'> var so = new SWFObject('/UI/Flash/player.swf', 'ply', '<%=FlashWidth %>', '<%=FlashHeight %>', '9', '#ffffff'), playlistURL = '<%=PlaylistURL %>', imageURL = '<%=GetBackgroundImageUrl() %>'; so.addParam('allowfullscreen', 'true'); so.addParam('allowscriptaccess', 'always'); if (playlistURL !== '') { so.addVariable('playlistfile', playlistURL); so.addVariable('playlist', 'none'); so.addVariable('enablejs', 'true'); } else { so.addVariable('file', '<%=FlashURL %>'); } if (imageURL.length > 0) { so.addVariable('image', imageURL); } so.write('preview<%=PlayerID %>'); </script>

  • Dynamically change ViewPagerIndicator titles

    - by msal
    My current project uses some ListFragments to show rows of data. The rows get updated dynamically every some seconds. The amount of rows varies with every update and in every ListFragment. I would like to show the amount of rows to the user, and think that the perfect place for that would be next to the Fragment's title in the ViewPagerIndicator. I provided a sample image for better comprehension: Sadly I am pretty clueless how to achieve this. I tried the following: public class PagerAdapter extends FragmentPagerAdapter { private int numOne = 0; private int numTwo = 0; // ... @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "List 1 (" + numOne + ")"; case 1: return "List 2 (" + numTwo + ")"; default: return ""; } public void setNumOne(int num) { this.numOne = num; } public void setNumTwo(int num) { this.numTwo = num; } } When I now call the setNumXXX() method, nothing happens, until I move between fragments, what seems to trigger the getPageTitle() to fire. My question is: How can I force an update of the title(s), everytime when the num value changes?

  • CSS opacity and child elements

    - by Rob
    <style type="text/css"> div#foo { background: #0000ff; width: 200px; height: 200px; opacity: 0.30; filter: alpha(opacity = 30); } div#foo>div { color: black; opacity:1; filter: alpha(opacity = 100); } </style> <div id="foo"> <div>Lorem</div> <div>ipsum</div> <div>dolor</div> </div> In the above example, the opacity of div#foo is inherited by child elements, causing the text to become nearly unreadable. I suppose it's wrong to say it is inherited, the opacity is applied to the parent div and the children are part of that, so attempting to override it for the child elements doesn't work because technically they are opaque. I typically just use an alpha png background image in such cases, but today i'm wondering if there's a better way to make a background of a div semi-transparent without affecting the contents.
