CSS Optimization causes problems in IE, Firefox, Not Chrome.

I second the Firefox report.

i got the same problems,and in IE ,the fontsize are very small.

I was ready to scrap the Deco theme! Thanks for posting this because I really wanted that look. Firefox only had a different font, but IE looked SO bad, like it had NO css! Disabling CSS optimization fixed it. Can anyone explain why?

This has to do with the style.css file. I believe this is caused by the @charset and @import declarations within the style.css file.

I solved this in style.css by REMOVING

@CHARSET "UTF-8";
@import "layout.css";
@import "icons.css";

Then in deco.info, BEFORE this line:
stylesheets[all][] = style.css

I added:

stylesheets[all][] = layout.css
stylesheets[all][] = icons.css

So my stylesheets section of deco.info looks like this:

stylesheets[all][] = layout.css
stylesheets[all][] = icons.css
stylesheets[all][] = style.css
stylesheets[print][] = print.css

Flush your cache and re-enable caching and it should work fine.

I was having the same issue and this helped out.

CSS import shoud not be used in order to optimize CSS files.

Thanks, this really works. :)

Looks like this was never an issue in the 7.x version of Deco.
