# Themes

> Browse, install, switch, and update community themes to change the visual style of Obsidian. Learn how to combine themes with CSS snippets for further customization.

Themes change the complete visual appearance of Obsidian — colors, fonts, spacing, and more. Hundreds of community-made themes are available directly inside the app, supporting both light and dark variants.

## Browse and install a theme

<Steps>
  <Step title="Open the theme browser">
    Go to **Settings → Appearance → Themes** and select **Manage**.
  </Step>

  <Step title="Choose a theme">
    Browse the list and select a theme to preview it. Themes respect your current color scheme (light or dark) and many ship with dedicated variants for both.
  </Step>

  <Step title="Install and apply the theme">
    Select **Install and use**. Obsidian installs the theme and immediately applies it.
  </Step>
</Steps>

## Switch or remove a theme

* **Switch themes:** Go to **Settings → Appearance → Themes → Manage**, select a different theme, and choose **Install and use**.
* **Revert to the default theme:** In the theme browser, select the currently active theme and choose **Stop using this theme**.
* **Uninstall a theme:** In the theme browser, select the theme and choose **Uninstall**.

## Update themes

Themes do not update automatically.

<Tabs>
  <Tab title="Update all themes">
    1. Go to **Settings → Appearance → Current community themes**.
    2. Select **Check for updates**.
    3. If updates are available, select **Update all**.
  </Tab>

  <Tab title="Update a single theme">
    1. Go to **Settings → Appearance → Themes → Manage**.
    2. Select the theme you want to update.
    3. Select **Check for updates**.
    4. If an update is available, select **Update**.
  </Tab>
</Tabs>

## Light and dark variants

Most community themes provide styling for both light and dark color schemes. The theme activates the correct variant based on your current color scheme setting in **Settings → Appearance → Base color scheme**.

To switch between light and dark mode independently of the theme, change the **Base color scheme** option.

## Customize a theme with Style Settings

Many community themes expose customization options through the **Style Settings** community plugin. After installing both the theme and the Style Settings plugin:

1. Go to **Settings → Style Settings** (added by the plugin).
2. Adjust the options exposed by your theme — for example, font choices, border radius, or heading colors.

<Tip>
  Not all themes support Style Settings. Check the theme's documentation or README to see what customization options it provides.
</Tip>

## Override theme styles with a CSS snippet

If you want to tweak just one or two aspects of a theme without modifying it directly, add a [CSS snippet](/extending/css-snippets). Snippets load after themes, so their rules take precedence.

For example, to change the heading color applied by the active theme:

```css theme={null}
/* my-tweaks.css */
body {
  --h1-color: #e06c75;
}
```

Place this file in `<vault>/.obsidian/snippets/` and enable it under **Settings → Appearance → CSS snippets**.
