Minify CSS

Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].

Reduce unused JavaScript

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript].

Eliminate render-blocking resources
