Basic usage

Setting the background origin

Use bg-origin-border, bg-origin-padding, and bg-origin-content to control where an element’s background is rendered.

bg-origin-border

bg-origin-padding

bg-origin-content

<div class="bg-origin-border p-4 border-4 border-dashed ..." style="background-image: url(...)"></div>
<div class="bg-origin-padding p-4 border-4 border-dashed ..." style="background-image: url(...)"></div>
<div class="bg-origin-content p-4 border-4 border-dashed ..." style="background-image: url(...)"></div>

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-origin-padding to only apply the bg-origin-padding utility on hover.

<div class="bg-origin-border hover:bg-origin-padding">
  <!-- ... -->
</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-origin-padding to apply the bg-origin-padding utility at only medium screen sizes and above.

<div class="bg-origin-border md:bg-origin-padding">
  <!-- ... -->
</div>
