IMPORTANT: Chromium decided to end support to custom stylesheets for the DevTools. As a result, this plugin is no longer working.

• /src/utils/styleBuilder.ts -> file that generates the :root CSS variables from the themes.json
• /src/devtools.svelte -> generates the :root inside the Devtools panel
• public/themes.yml -> Themes Manifest, will generate themes.json used by the extension

Releasing

1. Run plasmo:zip to create the zip file

npm run plasmo:zip

2. Bump the version in package.json

3. Upload the .plasmo/xxx.zip file to the Chrome Web Store

FAQ

I have installed the extension but nothing happened.

Make sure you've enabled the Chromium Experiment Allow extensions to load custom stylesheets, and reload the DevTools.

I selected the X theme but it looks ugly!

Please make sure you've selected the DARK or LIGHT theme in the DevTools settings, according to the selected theme.
