Ring Color

​Basic usage

​Setting the ring color

Use the ring-* utilities to set the color of an outline ring.

<button class="... ring-2 ring-blue-500">
  Create account
</button>

​Changing the opacity

Use the color opacity modifier to control the opacity of an element’s background color.

<button class="... ring-2 ring-blue-500/50">Subscribe</button>

You can use any value defined in your opacity scale, or use arbitrary values if you need to deviate from your design tokens.

<button class="... ring-2 ring-blue-500/[.55]">Subscribe</button>

​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-blue-500 to only apply the ring-blue-500 utility on hover.

<div class="ring ring-blue-300 hover:ring-blue-500">
  <!-- ... -->
</div>

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-blue-500 to apply the ring-blue-500 utility at only medium screen sizes and above.

<div class="ring ring-blue-300 md:ring-blue-500">
  <!-- ... -->
</div>

​Using custom values

​Customizing your theme

By default, Tailwind makes the entire default color palette available as ring colors. You can customize your color palette by editing theme.colors or theme.extend.colors in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      colors: {
        'regal-blue': '#243c5a',
      },
    }
  }
}

Alternatively, you can customize just your ring colors by editing theme.ringColor or theme.extend.ringColor in your tailwind.config.js file.

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

​Arbitrary values

If you need to use a one-off ring color 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-[#50d71e]">
  <!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
