Any chance of guidance for basic CSS modifications?

[danielrosehill]

Hey!

I'm working on editing the typography of my website built with Astro Paper.

I would like to edit some of the CSS classes like this to make the typeface used in the articles a bit bigger

And also change the font used for the article titles.

And finally increase the font size of the article previews on the homepage:

Is there any documentation available for where these classes might be found in the codebase?

TIA
