Typst is great for web content as well (even though their HTML export functionality is still experimental). I've written blog posts on interaction nets in Typst [0] and I really like how the diagrams look.
I rewrote my website to use typst for all the content and I really like how it is to integrate as well, its just a rust crate that I use in my build script because Typst is just on crates.io
