Open the avatar menu at the top right. **Appearance** sets the theme, **Accessibility** sets motion and text size, and **Language** sets the interface language.

## Switch between light and dark

1. Select your avatar.
2. Select **Appearance**. The item already shows the current setting, for example **Appearance: Dark**.
3. Select **Dark theme** or **Light theme**.

The same switch is on the **Preferences** page, labelled **Dark mode**, at `/en/account-page/preferences`.

## Reduce motion or change text size

1. Select your avatar, then **Accessibility**.
2. Under **Motion**, choose **Use device setting** or **Reduce motion**.
3. Under **Text size**, choose a size.

**Use device setting** follows the reduced-motion preference your operating system reports.

## Change the language

1. Select your avatar, then **Language**. The item shows the current language.
2. Type in **Search languages...** or pick from the list.

Help pages are written in English whatever language the interface is set to.

## If it did not work

- Theme, language and text size are stored per browser. A different browser or a private window starts from the defaults again.
- Signing out keeps your theme, language and sidebar preferences; it clears everything else for that browser.
- **No languages found** means nothing matches what you typed in the search box. Clear it and scroll the list.
