I especially agree on the heading part. More space before headers would make sections much easier to distinguish.
Some way to differentiate code blocks from normal text, such as the background color used in Github, would also be nice.
+1. Additionally, heading levels 2 and 3 look too similar in my opinion.
I appreciate the minimalism, but completely agree. Margins and some way to distinguish between code blocks and prose would be great for accessibility.
Something similar to the
.eventclass already used throughout would maybe work to keep things stylistically cohesive.
