Content Container Overlaps Menu?
- by Harold
I'm currently working on a Joomla template using CSS divs. I have a header set up with our logo image in a div floated to the left, an adspace floated to the right, and the menu bar on the bottom.
My content is divided into three div columns that are contained in "container.": the left column is floated left, the center is not floated, and the right is floated to the right.
The problem is the "container" for the three content divs is overlapping the menu, as you can see in this image: http://www.ndpstudentcouncil.org/images/shot1.png
Here's the HTML code:
> <body> <div id="backdrop"> <div
> id="wrapper"> <div id="header">
> <div id="topimage"> </div>
> <div id="adspace1"><jdoc:include
> type="modules" name="Ad Space #1" />
> This will be the location for our
> "newsflash" items. </div>
>
> <div id="ddtopmenubar"
> class="mattblackmenu">
> <ul>
> <li><a href="http://www.ndpstudentcouncil.org">Home</a></li>
> <li><a href="http://www.dynamicdrive.com/new.htm" rel="ddsubmenu1">DHTML</a></li>

> <script type="text/javascript" src="js/ddlevelsmenu.js">

> </ul>
> </li>
> </ul>
> </a>
> </li>
> <li><a href="#">Item 6a</a></li>
> </ul> </div> </div>
> <div id="container"> <script language="javascript">

The CSS:
> #backdrop { width:100%; height:100%; background: #FFFFFF
> url(../images/gradient.jpg) repeat-x;
> }
>
> #wrapper { margin:auto; width:95%; height:95%; border-right:thick solid
> black; border-bottom:thick solid
> black; border-top:thick solid black;
> border-left:thick solid black;
> background-color:white; }
>
> #header { height:131px; width:100%; background-color: #FFFFFF;
> border-bottom:thick solid black; }
>
> #topimage { float:left; height:131px; width:63%;
> background-image:
> url("../images/ndps2.png");
> background-repeat:no-repeat; }
>
> #adspace1 { float:right; width:27%; height:131px; }
>
> #container { clear:both; }
> #left{ width:20%; float:left; padding:5px; text-align:center; }
>
> #middle{ width:60%; padding:5px; text-align:center; }
>
> #right{ float:right; width:20%; padding:5px; text-align:right; }
> #footer { border-top:thick solid black; width:100%;
> text-align:center; } .clear {
> clear:both; }
Here is the CSS for the menu itself, which is from DynamicDrive.com:
> .mattblackmenu ul{ margin: 0; padding:
> 0; font: bold 12px Verdana;
> list-style-type: none; border-bottom:
> 1px solid gray; background: #414141;
> overflow: hidden; width: 100%;
> clear:both; }
>
> .mattblackmenu li{ display: inline;
> margin: 0; }
>
> .mattblackmenu li a{ float: left;
> display: block; text-decoration: none;
> margin: 0; padding: 6px 8px; /*padding
> inside each tab*/ border-right: 1px
> solid white; /*right divider between
> tabs*/ color: white; background:
> #414141;
Thanks for the help!
