I'm definitely going to steal your website design (please don't sue me). But I don't like sans-serif fonts. What serif fonts do you recommend to use instead?
I don't care and am instead flattered :) Would appreciate a mention in the comments if you indeed do, though.
As for serif fonts, I would recommend doing what the other comment suggests. To expand on that, if you find that a particular safe web font [1] looks better for your site, you can explicitly prioritize it. For example, I did Arial -> Helvetica -> sans-serif.
