Basic usage

Setting the outline color

Use the outline-* utilities to change the color of an element’s outline.

outline-blue-500

outline-cyan-500

outline-pink-500

<button class="outline outline-offset-2 outline-blue-500 ...">Button A</button>
<button class="outline outline-offset-2 outline-cyan-500 ...">Button B</button>
<button class="outline outline-offset-2 outline-pink-500 ...">Button C</button>

Changing the opacity

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

outline-blue-500/50

<button class="outline-2 outline-blue-500/50 ...">Save Changes</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="outline-4 outline-pink-400/[.55] ..."></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:outline-blue-400 to only apply the outline-blue-400 utility on hover.

<button class="outline hover:outline-blue-400">
  <!-- ... -->
</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:outline-blue-400 to apply the outline-blue-400 utility at only medium screen sizes and above.

<button class="outline md:outline-blue-400">
  <!-- ... -->
</button>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

Using custom values

Customizing your theme

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

tailwind.config.js

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

Alternatively, you can customize just your outline colors by editing theme.outlineColor or theme.extend.outlineColor 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 outline-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.

<button class="outline-[#243c5a]">
  <!-- ... -->
</button>

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