GitHubDHC

A GitHub Dark High Contrast theme for Obsidian!

Report Bug · Request Feature

I do a lot of writing in Markdown, mostly for things that I'm doing up on GitHub. (Obsidian is an great editor for this). I was running into some frustration with the formatting not mapping really well between Obsidian and GitHub, when I thought, "there has to be a theme for this!" I found @krios2146's awesome Obsidian GIthub Theme.

It was close, but not really the way my GitHub looks (I use the GitHub Dark High Contrast theme when I'm working online), so I decided to start hacking the css a bit to see how close I could get. The look of GitHubDHC is different enough from the original theme that I decided to start a new fork based on Vladimir's really nicely done Obsidian GitHub Theme -- it's worth checking out - he did all the initial work and the Kanban theme'ing - it's really good.

Features (v2.0)

• Dual Theme Support: Full support for both Dark High Contrast and Light Default themes
• Accurate GitHub Colors: Uses official GitHub Primer color primitives for authentic appearance
• Enhanced UI Components (for settings dialog, Obsidian UI, etc.):
  • Form elements (dropdowns, inputs) now match GitHub styling
• GitHub-Style Callouts
• Improved Typography: Bold navigation items and better text hierarchy
