# Theme

The framework is built on [shadcn-vue](https://www.shadcn-vue.com/themes.html) and [tailwindcss](https://tailwindcss.com/), offering a rich theme configuration. You can easily switch between various themes through simple configuration to meet personalized needs. You can choose to use CSS variables or Tailwind CSS utility classes for theme settings.

## CSS Variables

The project follows the theme configuration of [shadcn-vue](https://www.shadcn-vue.com/themes.html), for example:

```html
<div class="bg-background text-foreground" />
```

We use a simple convention for colors. The `background` variable is used for the background color of components, and the `foreground` variable is used for text color.

For the following components, `background` will be `hsl(var(--primary))`, and `foreground` will be `hsl(var(--primary-foreground))`.

## Detailed List of CSS Variables

::: warning Note

The colors inside CSS variables must use the `hsl` format, such as `0 0% 100%`, without adding `hsl()` and `,`.

:::

You can check the list below to understand all the available variables.

## Overriding Default CSS Variables

You only need to override the CSS variables you want to change in your project. For example, to change the default card background color, you can add the following content to your CSS file to override it:

### Under the Default Theme

```css
:root {
  /* Background color for <Card /> */
  --card: 0 0% 30%;
}
```

### In Dark Mode

```css
.dark,
.dark[data-theme='custom'],
.dark[data-theme='default'] {
  /* Background color for <Card /> */
  --card: 222.34deg 10.43% 12.27%;
}
```

## Changing the Brand Primary Color

::: tip

- You need to use the `hsl` color format.
- You must clear the cache for the changes to take effect.
- You can use [third-party tools](https://www.w3schools.com/colors/colors_hsl.asp) to convert colors.

:::

You only need to customize the primary color in the `preferences.ts` file under the application directory:

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  theme: {
    // Error color
    colorDestructive: 'hsl(348 100% 61%)',
    // Primary color
    colorPrimary: 'hsl(212 100% 45%)',
    // Success color
    colorSuccess: 'hsl(144 57% 58%)',
    // Warning color
    colorWarning: 'hsl(42 84% 61%)',
  },
});
```

## Built-in Themes

The framework includes a variety of built-in themes, which you can configure in the `preferences.ts` file:

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  theme: {
    builtinType: 'default',
  },
});
```

### Built-in Theme List

The framework includes 16 built-in themes and also supports custom themes. Theoretically, you can expand the themes without limit.

::: details List of Built-in Theme Types

```ts
type BuiltinThemeType =
  | 'custom'
  | 'deep-blue'
  | 'deep-green'
  | 'default'
  | 'gray'
  | 'green'
  | 'neutral'
  | 'orange'
  | 'pink'
  | 'red'
  | 'rose'
  | 'sky-blue'
  | 'slate'
  | 'stone'
  | 'violet'
  | 'yellow'
  | 'zinc'

## Adding a New Theme

To add a new theme, simply follow these steps:

- Add a new theme configuration in the application's `src/preferences.ts`.

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  theme: {
    builtinType: 'my-theme',
  },
});
```

## Dark Mode

The framework includes a variety of built-in themes, which you can configure in `preferences.ts`. The dark theme also uses CSS variables for configuration:

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  theme: {
    mode: 'dark',
  },
});
```

## Customizing Sidebar Color

The sidebar color is configured through the `--sidebar` variable.

### Under the Default Theme

```css
:root {
  --sidebar: 0 0% 100%;
}
```

### In Dark Mode

```css
.dark,
.dark[data-theme='custom'],
.dark[data-theme='default'] {
  --sidebar: 222.34deg 10.43% 12.27%;
}
```

## Customizing Header Color

The header color is configured through the `--header` variable.

### Under the Default Theme

```css
:root {
  --header: 0 0% 100%;
}
```

### In Dark Mode

```css
.dark,
.dark[data-theme='custom'],
.dark[data-theme='default'] {
  --header: 222.34deg 10.43% 12.27%;
}
```

## Color Weakness Mode

Typically used in special scenarios, you can set the application to color weakness mode. This can be configured in `preferences.ts`:

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  app: {
    colorWeakMode: true,
  },
});
```

## Gray Mode

Typically used in special scenarios, this mode grays out the webpage. You can configure it in `preferences.ts`:

```ts
import { defineOverridesPreferences } from '@vben/preferences';

export const overridesPreferences = defineOverridesPreferences({
  // overrides
  app: {
    colorGrayMode: true,
  },
});
```
