Question: Can I import a css file into all pages?

[ReiSuzuki]

I've added a css file to the assets setting, but how can I add them to the page to customize the look and feel?

A custom stylesheet can probably only be used on pages where you directly control the HTML, for example, on a custom home page. Otherwise, apexdox generates the markup and classnames and uses its default styling.
