> it turns out that IE has a limit to the size of a CSS file. It's not the 
> actual size of the file, but rather it is the
> # of CSS selectors. I did a test and found out that the limit is 4095 CSS 
> selectors.
> Firefox doesn't appear to have a limit.
> As you may know, the CSS file we generate contains both compressed and 
> uncompressed styles, like this:
> .af_inputText_content, .x01 {background-color: blue}
> Our renderers render a shortened styleclass, unless
> the DISABLE_CONTENT_COMPRESSION flag is set to true in web.xml, then it 
> renders the long styleclass.
> <input class="x01...>
> Ok, that's the background.
> *The problem* is that because we have a lot of custom components that we've 
> built on top of Trinidad, and our customers
> have built custom components, etc, and these all have skinning,
> we have bumped up against the 4095 selector limit in IE. All selectors after 
> the 4095th one are ignored.
> *A quick fix*, and probably a good one for a long time, is to render the 
> styles in compressed mode when compression is on,
> or in uncompressed mode when compression if off. That will reduce our style 
> selectors by 1/2, and will help performance to boot. :)
> I can also add a warning if we go past 4095 selectors for IE.
> Another solution is to break up the file into multiple files when I've 
> reached the limit in one file, and include
> all the css files into the rendered page. I can do this in addition to the 
> quick fix when I have more time.
