Does IE9 have a file size limit for CSS?

css, internet-explorer, internet-explorer-9, stylesheet

Solution

There are 3 limits:

- a sheet may contain up to 4095 selectors, see http://demos.telerik.com/testcases/4095issues.html

- a sheet may @import up to 31 sheets, see http://demos.telerik.com/testcases/BrokenTheme.aspx

- @import nesting supports up to 4 levels deep

Problem

I'm using Drupal and I notice that if I have my CSS files aggregated that the CSS doesn't always work correctly. I know there is a problem in IE7 but is there a limit to a CSS file size in IE9?
