rounded-r

The rounded-r class in Tailwind CSS applies the default border-radius to the right side of an element — specifically the top-right and bottom-right corners. It’s useful when you want smooth rounding on one side only, such as in button groups, input fields, or card edges.

Syntax

html
<div class="rounded-r">...</div>

Example Code

html
<div class="flex">
  <input type="text" class="border px-4 py-2 rounded-l" placeholder="Email" />
  <button class="bg-blue-600 text-white px-4 py-2 rounded-r">
    Subscribe
  </button>
</div>

Preview

In this case, rounded-r gives the button a rounded right edge, while rounded-l shapes the input's left side — perfect for building grouped elements.

How to Use

Add the rounded-r class directly to your HTML element:

html
<div class="rounded-r">
  <!-- Your content here -->
</div>

Responsive Usage

Use Tailwind's responsive prefixes to apply rounded-r at specific breakpoints:

html
<div class="sm:rounded-r md:rounded-r lg:rounded-r">
  Responsive element
</div>
  • sm:rounded-r — applies from 640px and up
  • md:rounded-r — applies from 768px and up
  • lg:rounded-r — applies from 1024px and up
