Technically "it depends on the browser settings," but the body font Alegreya is served directly by the site, so I think it would be the one used in almost all cases.

The math fonts used in the formulas are just the ones provided by KaTeX, which I think are just TeX's default math fonts.

Already replied :)

The source code of the website is open if you wanna check it out!

Thanks. Your website looks really nice!

Glad that you like it :)

Today I learned there's a CSS property for styling the first letter of a paragraph, neat. (https://css-tricks.com/almanac/properties/i/initial-letter/)

--edit: The font used for those initials is called Goudy Initialen: https://www.dafont.com/goudy-initialen.font

I love this -- I'll have to do something like that for my site. I always liked the big initials on the start of a paragraph. Though it feels a bit more prose-applicable than for non-fiction writing.

That font, and how it's integrated with the math looks amazing. Katex for the math?

Seems like Katex from the scripts getting loaded. I love the design too, kinda medieval-chic.

Looks more early modern to me. :)
