Custom Theme Studio

Build your own Obsidian theme from inside Obsidian. Change any of Obsidian's CSS variables, write CSS rules with a proper code editor, click on things to get their selectors, and export the result as a theme you can install or share.

Requires Obsidian 1.13.0 or later and a desktop device. For older versions of Obsidian, install an earlier release of the plugin manually.

What you can do

• Edit CSS variables. Every built-in Obsidian variable is listed with its default value, grouped by category and searchable. Change a value and see it right away. Add your own variables too.
• Write CSS rules. Save named pieces of CSS that you can switch on and off. The editor has syntax highlighting, Prettier formatting, and optional autocomplete and color picker.
• Pick elements visually. Hover over any part of Obsidian to see its classes and attributes, then click to start a rule with a selector already written.
• Import fonts and snippets. Embed font files as @font-face rules, or pull in CSS snippets you already have.
• Export a theme. Download theme.css and manifest.json, ready to drop into your themes folder.
• Back up your work. Export all your settings to a file in your vault and import them again later or in another vault.

See the user guide for how everything works.

Installation

From Obsidian

1. Open Settings > Community plugins and click Browse.
2. Search for "Custom Theme Studio", install it, and enable it.

Or open it on community.obsidian.md.

Manually

1. Download main.js, manifest.json, and styles.css from the latest release.
2. Create the folder <your vault>/.obsidian/plugins/custom-theme-studio and put the three files in it.
3. In Settings > Community plugins, reload the list of installed plugins and enable Custom Theme Studio.

Getting started

1. Click the paintbrush icon in the left ribbon, or run Custom Theme Studio: Open view from the command palette.
2. Turn on Enable theme at the top of the view.
3. Change a variable, or click Select an element under CSS rules and click something you want to restyle.

A few tips:

• Export your settings (Settings > Custom Theme Studio > Backup) before big changes.
• If a rule breaks the layout, run Toggle custom theme from the command palette to turn everything off while you fix it.
• For menus and hover states that vanish when you move the mouse, use the Freeze Obsidian command.
