Glad you've found it useful!

Great job! You saved my day!

I like the look for the most part, but when I paste this CSS into IDEA's custom Markdown CSS rules, general body text comes out very faint. I've tried to tweak the CSS myself but the faint text remains.

I understand what's happening now, but I don't know how to fix it, or if it can be fixed. The body text color above is coming from the dark theme I'm using for IDEA in general.

I want to keep using that dark theme, however, for coding and everything else other than Markdown previews, which I want to have looking like Github Markdown.

Is there any CSS than can override the text coming from my current IDEA theme?

I can fix a lot of the faint text issues by adding:

p, ul, li {
  color: #333;
}

But colors within code fences are still coming from the IDE's current theme.

Ah... I see I can change Markdown documents alone to use a light theme while everything else uses a dark theme, and then the CSS above looks great. Thank you for providing it.

The only drawback is that this way it's not only the preview but the raw Markdown that takes on the light theme. I can live with this, but ideally I'd like only the preview to be light while I edit dark-background text.

I was wrong thinking I could change the color scheme for only one file type. I just didn't realize right away that I'd changed the color scheme for all file type code editors because the borders of my IDE remained dark-themed after I made the change.

So, later on...

I found out how to export an HTML version of a Markdown preview, and the news from that was not good. Each individual token inside the code fences had an explicit styled color like this:

<span md-src-pos="2424..2432" style="color: rgb(207, 142, 109);">function</span>

...without having a class to override to define its appearance. The best I could do having seen this was to add:

blockquote, li, p, pre, table, td, th, ul {
  color: #333 !important;
}

code span {
  color: #333 !important;
}

This destroys all syntax color coding, but at least ensures that all text inside code fences is clear and legible no matter what your current IDE theme might be.

Here's my own version of GitHub CSS for Jetbrains products, derived from the above but altered a fair amount too, containing both light and dark themes, and designed for a (possible) future where GitHub syntactical color can be closely matched.
