Is there a CSS file size limit in IE9?
I was trying to research the file size limit in IE9. There are many anecdotal links about one existing one (mostly the 288KB limitation), but I could not find any proper documentation on any of them. There were about the same number of people who said that they exist as people, who said that they do not exist.
Some links on both sides:
Thought of existence:
I don't think this exists:

- https://spaceninja.com/2015/03/31/ie-css-limits/
The official Microsoft documentation does not specify this limit, but it also does not disprove its existence. I made a test file that had 1 CSS rule, lots of free space to get it up to 300KB, and then a second rule. The second rule was applied. I'm still confused when this notion of this 288K limit came from.
Given that it is 2018, there should be some consensus around this limit, right? Does anyone know if this limit exists or not? If so, I would like some formal proof of this. If this is not the case, I would like to know where this idea came from.
Please do not mark this as a duplicate unless you provide me with a link that definitively provides a source of information on what this limit is, or proves that it does not exist.

After extensive testing and research, I have to conclude that there is no such limitation for IE9. Why there are many rumors about this on the internet I have no idea, but I could not find any official documentation on this fact. Any speculation about this fact has simply not been confirmed by stack overflow comments or random blog posts. After creating my own CSS that was above 288KB and seeing that it successfully loads all the rules, I can't see how this limitation could exist. These people may have hit the selection limit, but I can't investigate further as there are no files that exist that exceed 288KB, don't fall within the selector limit, and presumably don't fully load in IE9. I hope that future developers can see this question,not wasting so much time on this random IE9 tidbit like mine.
