Question

Removeable side bar layout possible without CSS expression?

Answer 1

+1 A:

The + adjacency selector would do it, except in IE6 where it isn't supported. The usual workaround would be to add some extra class information:

<div id="container" class="with-sidebar">

and then select on that in the stylesheet:

#sidebar { float: left; width: 130px; }
.with-sidebar #main { margin-left: 130px; }

This needs to expand to fill available width

Then don't bother make it float; I'm not sure what that's supposed to achieve.

Also avoid ‘inherit’ rules, they don't work in IE previous to version 8.

Thanks - I thought I needed to float the layers so they would position next to one another (`#sidebar` next to `#main`) instead of one below the other.

A:

You must use JavaScript instead. Just set the width to some value in the CSS part and then, you can modify the style of the DIV to override it:

document.getElementByID("main").styles.width = "100%";

.with-sidebar #main {

<body>
<div id="container" class="with-sidebar">
    <div id="sidebar"><p>This is the side bar</p></div>
    <div id="main"><p>This needs to expand to fill available width.</p></div>
</div>
</body>

(You can lose the #sidebar+#main adjacency rule too, since the class workaround will work on all browsers.)
