performance - Unused classes in my HTML -


do unused class names on html elements impede rendering performance (with no corresponding style in style).

eg: have number of game types have fixed number set, game types require number set styled differently. game type key added parent of game types allow number set styled differently each game type if required, although use default styling such have unused classes.

not on active performance. give stylesheets more data-weight download, might seem trivial if count in browser-caching.

classes lazy-loaded , aren't chunked in whole rendering-set of browser. searched when needed. if never used, not impact performance of website.

there's 1 final note tho; if use different class chains (.abc .def:nth-child(1) .ghi) complex selectors, might take browsers bit time (fractions of miliseconds) try still figure out what's happening tho. need benchmark these situations , may differ per browser.
