Styles are slow, that is a fact. To fix this WP Core Web Vitals minifies, compresses, optimizes & redistributes CSS files. Use automatic Critical CSS that works out of the box for ultra fast first pageviews and leverage browser caching for even faster repeat pageviews! Fix the time gap caused  by the slowest file with redistributed optimized css files. Save critical connection time and automatically self-host all your slow external CSS files!
