Warum ist das wichtig?

Large amounts of inline CSS/JS cannot be cached by the browser, are resent with every page request and increase HTML file size. This increases load time and slows down Time To Interactive.

Wie beheben Sie es?

Move repeated inline styles to external CSS files. Move inline scripts to external JS files with defer. Small critical CSS that determines above-the-fold styling may remain inline.
