I think we should not use Monospace fonts for the Markdown Editor since we are not coding.
Similar to Github, code-blocks and inline-code only gets converted to monospace in the Preview.
- better symmetry
- less spacing to the left and right, since it's common to already have a space in the sentence (even if it doesn't, like in CJK, the new spacing looks sufficient).
Quotes should be subtle as it is primarily intended for redundant content, but currently it looks more like a banner that brings lots of focus.
This change is also background-independent. Currently, the Quotes in Posts doesn't look like it has a background color, because it happened to be the same as the Post's background. This makes it inconsistent with Quotes in Comments. Let's just always make it blend in + grayish text.
