Suggested Changes

The red text on green line background in the color diffs has a color contrast ratio of 3.38:1 (#FF0000 on #B8FAE0), which is not strong enough for all users to be able to perceive the text. We should up the contrast to make sure the lines are readable by everyone - at least 4.5:1. See https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum.html for accessibility docs.

(I personally found it a little difficult at first to read such a bold green background.)

Suggestion: how about darkening the code text to #DD0000, halving the opacity of the green background to 00ff9520, and making the + glyphs bold?
