## Components

### `app.config.ts`
|
||||
|
||||
Components are styled with Tailwind CSS but classes are all defined in the default [app.config.ts](https://github.com/nuxtlabs/ui/blob/dev/src/runtime/app.config.ts) file. You can override those in your own `app.config.ts`.

### `ui` prop

You can find the default classes for each component under the `Preset` section.

Thanks to [tailwind-merge](https://github.com/dcastil/tailwind-merge), the `ui` prop is smartly merged with the config. This means you don't have to rewrite everything. :u-badge{label="Edge" class="!rounded-full" variant="subtle"}
|
||||
|
||||
For example, the default preset of the `FormGroup` component looks like this:
|
||||
|
||||
```json
|
||||
{
|
||||
...
|
||||
"label": {
|
||||
"base": "block font-medium text-gray-700 dark:text-gray-200",
|
||||
...
|
||||
}
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
To change the font of the `label`, you only need to write:
|
||||
|
||||
```vue
|
||||
<UFormGroup name="email" label="Email" :ui="{ label: { base: 'font-semibold' } }">
|
||||
...
|
||||
</UFormGroup>
|
||||
```
|
||||
|
||||
This will smartly replace the `font-medium` by `font-semibold` and prevent any class duplication and any class priority issue.
|
||||
|
||||
### `class` attribute
|
||||
|
||||
You can also use the `class` attribute to add classes to the component.
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<UButton label="Button" class="rounded-full" />
|
||||
</template>
|
||||
```
|
||||
|
||||
Again, with [tailwind-merge](https://github.com/dcastil/tailwind-merge), this will smartly merge the classes with the `ui` prop and the config. :u-badge{label="Edge" class="!rounded-full" variant="subtle"}
|
||||
|
||||
### Default values
|
||||
|
||||
Some component props like `size`, `color`, `variant`, etc. have a default value that you can override in your `app.config.ts`.
|
||||

||||
