Somewhat off topic, but it annoys me that CSS resets kill the margins on p, h1, h2, and ul. As well as the list-style.

I basically don’t use those elements for UI components, and in the rare cases where I would want to, I could just do a one-off to override them. Or, more likely I’d just do something like <div role="heading" aria-level="1">

I find in applications you eventually need some little places where you have some basic document styles: paragraphs, headings, bullets, and it’s nice to be able to use those basic semantic tags for that stuff.
