The solution in (https://github.com/discourse/discourse/pull/30547)
using `em` units was causing readability problems for code blocks in
mobile. This reverts to the previous solution
(https://github.com/discourse/discourse/pull/30536) of using `font-size:
inherit` for code within heading elements.
The downside is that the code in heading won't be slightly smaller than
the other text like it is for inline code in paragraphs, but it seems
worth it to avoid causing other size issues.
In modern hljs, languages should be targetted with `lang-` prefixes. These selectors haven't worked in Discourse for a long time, so let's drop them to reduce confusion
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets.
This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.
Run `prettier --write "app/assets/stylesheets/**/*.scss" "plugins/**/*.scss"` after making sure you installed it with `yarn`
It's recommended to configure your editor to run prettier on file save.
