Accessibility issues

[with-heart]

Looooooove what you're doing with your blog. It's one of my favorite things on the internet!

While looking through it and poking around, I noticed some UX issues that I wanted to report:

Pop quiz in dark mode isn't readable

(hovered button on left, selected button on right, success text underneath)

Looks great in light mode though:

Lacking focus indicators for keyboard navigation

Here's a screencapture of me tabbing my way through part of the page:

Aside from links, buttons from the code previews, and accordion headers, there's no focus indicator to tell me what I currently have selected. Makes it almost impossible to navigate effectively with a keyboard!
