@Felthry This is a CSS rule. CSS is laid out roughly like so:
<element restriction> {
<thing to change>: <change> <modifier>;
}
In this case, it's saying
<All elements> {
<font boldness>: <standard> !<even if later rules try to make something bold or thin>;
}
Basically, that rule makes it so that bold tags like <b> or <strong> just simply don't work the way they're supposed to
@mawr @Felthry About the only way I'd accept it is if it came out of a userscript file. Then it'd make sense.
I have several small scripts for preventing sites from overriding user-selected fonts, including for Mastodon-related sites. Fortunately, Mastodon isn't guilty of !important abuse. Someday I'll run across some site that thinks its body-text font is worth a double !important, and I will call upon dark forces to retaliate.
The _darkest_ forces. *cute little pegasus-pony stamps her hoof*
