Setting the background position

Applying conditionally

Hover, focus, and other states

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

  1. <div class="bg-center hover:bg-top ..." style="background-image: url(...)"></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:bg-top to apply the bg-top utility at only medium screen sizes and above.

  1. <div class="bg-center md:bg-top ..." style="background-image: url(...)"></div>

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 provides nine background-position utilities. You change, add, or remove these by editing the theme.backgroundPosition section of your Tailwind config.

tailwind.config.js

  1. module.exports = { theme: { backgroundPosition: { bottom: 'bottom', 'bottom-4': 'center bottom 1rem', center: 'center', left: 'left', 'left-bottom': 'left bottom', 'left-top': 'left top', right: 'right', 'right-bottom': 'right bottom', 'right-top': 'right top', top: 'top', 'top-4': 'center top 1rem', } }}

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

Arbitrary values

If you need to use a one-off background-position 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.

  1. <div class="bg-[center_top_1rem]">
  2. <!-- ... -->
  3. </div>

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