Performance: Pure CSS vs jQuery

Question

I\'ve seen a number of code comparisons between pure CSS and the equivalent jQuery. But I\'m looking for details about why pure CSS is definitively faster than jQuery.

Answer 1

I think the main reason CSS is faster is because it can be optimized more than javascript because it is less complicated, the code is just a series of rules and doesn't have much of its own logic (other than selectors and the occasional calc() function) BTW, CSS definitely does have to be evaluated by the browser.
