Is converted into a page. Her huge css code, 20,000 lines (concatenating and minimized). A large part of the page is not needed. Heard there are services that analyze the css is loaded and after the analysis derive simplified css code that is actually used on this page, removing all the excess that is not used.
Tell me, please, is it true there are such things and how to find them. Maybe you know what they are called, the reference ponakidayut.
