I realize you're all busy at Fosdem and whatnot and that it's Kaffee and Kuchen time, but the first person to teach me why my trivial CSS at https://owntracks.org/booklet/extra.css styles h2 in green but code not in yellow at https://owntracks.org/booklet/tech/json/ wins an honorable mention in said CSS file.
The colors can cause headaches, but it's my way of debugging.
Edit: Gergely Nagy wins:
/*

.rst-content code {
color: yellow;
}
