Is there a CSS file size limit in IE9?

Question

I was trying to research a file size limit in IE9. There are many anecdotal links about one existing (mostly 288KB limit ones), but I could not find any proper documentation

Answer 1

After extensive testing and research, I have to conclude that no such limit exists for IE9. Why there are many rumors on the internet about it, I have no clue, but I could not find any official documentation of the fact. Any suggestion of this fact has just been unsupported Stack Overflow comments or random blog posts. After making my own CSS that was over 288KB, and seeing it successfully load all rules, I don't see how this limit could exist. It's possible these people were hitting the selector limit, but I can't investigate further as there are no files that exist that are over 288KB, don't hit the selector limit, and are purported to not fully load in IE9. I hope future developers can see this question, and not waste as much time on this random IE9 tidbit as I have.
