Ring Offset Width

​

Basic usage

​

Setting the ring offset width

Use the ring-offset-{width} utilities to simulate an offset by adding solid white box-shadow and increasing the thickness of the accompanying outline ring to accommodate the offset.

<button class="... ring ring-pink-500 ring-offset-0">Button A</button>
<button class="... ring ring-pink-500 ring-offset-2">Button B</button>
<button class="... ring ring-pink-500 ring-offset-4">Button C</button>

​

Changing the offset color

You can’t actually offset a box-shadow in CSS, so we have to fake it using a solid color shadow that matches the parent background color. We use white by default, but if you are adding a ring offset over a different background color, you should use the ring-offset-{color} utilities to match the parent background color:

<button class="ring ring-pink-500 ring-offset-2 ring-offset-slate-50 dark:ring-offset-slate-900 ...">
  Save Changes
</button>

For more information, see the ring offset color documentation.

​

Applying conditionally

​

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:ring-offset-4 to only apply the ring-offset-4 utility on hover.

<button class="ring-2 ring-offset-2 hover:ring-offset-4">
  <!-- ... -->
</button>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:ring-offset-4 to apply the ring-offset-4 utility at only medium screen sizes and above.

<button class="ring-2 ring-offset-2 md:ring-offset-4">
  <!-- ... -->
</button>

​

Using custom values

​

Customizing your theme

To customize which ring offset width utilities are generated, add your custom values under ringOffsetWidth key in the theme section of your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      ringOffsetWidth: {
        '3': '3px',
        '6': '6px',
        '10': '10px',
      }
    }
  }
}

Learn more about customizing the default theme in the theme customization documentation.

​

Arbitrary values

If you need to use a one-off ring-offset value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="ring-offset-[3px]">
  <!-- ... -->
</div>
