Question

what is the max number css rules I can specify in style sheet per browser.

Answer 1

Are you talking about how many css includes you can do? IE does have a maximum of 32 (source) or maybe 31.

However it sounds like you are asking if there is a maximum amount of styles you can include in a single .css file, and I am not aware of any limit in that respect.

Answer 2

There's no official limit for any browser, but Internet Explorer has a couple of "unofficial" limits:

• Maximum number of external stylesheets per page is 32,
• Maximum number of rules per stylesheet is reportedly 4096.

I'm not aware of any limits in other browsers, but in theory a very large file could cause issues in any of them.
