IE CSS bug: table border showing div with visibility: hidden, position: absolute
- by Alessandro Vernet
The issue
I have a <div> on a page which is initially hidden with a visibility: hidden; position: absolute. The issue is that if a <div> hidden this way contains a table which uses border-collapse: collapse and has a border set on it cells, that border still shows "through" the hidden <div> on IE.
Try this for yourself by running the code below on IE6 or IE7. You should get a white page, but instead you will see:
Possible workaround
Since this is happening on IE and not on other browsers, I assume that this is an IE bug. One workaround is to add the following code which will override the border:
.hide table tr td {
border: none;
}
I am wondering:
Is this a known IE bug?
Is there a more elegant solution/workaround?
