# Checkbox

Checkboxes allow the user to toggle an option on or off.

```html preview
<sl-checkbox>Checkbox</sl-checkbox>

```html preview
<sl-checkbox indeterminate>Indeterminate</sl-checkbox>
```

### Sizes

Use the `size` attribute to set the size of the checkbox.

```html preview
<sl-checkbox size="small">Small</sl-checkbox>
<sl-checkbox size="medium">Medium</sl-checkbox>
<sl-checkbox size="large">Large</sl-checkbox>

```

### Disabled
