Rounded corners

Use utilities like .rounded-sm, .rounded, or .rounded-lg to apply different border radius sizes to an element.

.rounded-sm
.rounded
.rounded-md
.rounded-lg
<div class="rounded-sm ..."></div>
<div class="rounded ..."></div>
<div class="rounded-md ..."></div>
<div class="rounded-lg ..."></div>

Pills and circles

Use the rounded-full utility to create pills and circles.

Pill Shape
Circle
<div class="rounded-full py-3 px-6...">Pill Shape</div>
<div class="rounded-full h-24 w-24 flex items-center justify-center...">Circle</div>

No rounding

Use rounded-none to remove an existing border radius from an element.

This is most commonly used to remove a border radius that was applied at a smaller breakpoint.

.rounded-none
<div class="rounded-none ...">.rounded-none</div>

Rounding sides separately

Use rounded-{t|r|b|l}{-size?} to only round one side of an element.

.rounded-t-lg
.rounded-r-lg
.rounded-b-lg
.rounded-l-lg
<div class="rounded-t-lg ...">.rounded-t-lg</div>
<div class="rounded-r-lg ...">.rounded-r-lg</div>
<div class="rounded-b-lg ...">.rounded-b-lg</div>
<div class="rounded-l-lg ...">.rounded-l-lg</div>

Rounding corners separately

Use rounded-{tl|tr|br|bl}{-size?} to only round one corner an element.

.rounded-tl-lg
.rounded-tr-lg
.rounded-br-lg
.rounded-bl-lg
<div class="rounded-tl-lg ..."></div>
<div class="rounded-tr-lg ..."></div>
<div class="rounded-br-lg ..."></div>
<div class="rounded-bl-lg ..."></div>

Responsive

To control the border radius of an element at a specific breakpoint, add a {screen}: prefix to any existing border radius utility. For example, use md:rounded-lg to apply the rounded-lg utility at only medium screen sizes and above.

<div class="rounded md:rounded-lg ...">
  <!-- ... -->
</div>

Customizing

Border Radiuses

By default, Tailwind provides five border radius size utilities. You can change, add, or remove these by editing the theme.borderRadius section of your Tailwind config.

  // tailwind.config.js
  module.exports = {
    theme: {
      borderRadius: {
        'none': '0',
-       'sm': '0.125rem',
-       DEFAULT: '0.25rem',
+       DEFAULT: '4px',
-       'md': '0.375rem',
-       'lg': '0.5rem',
-       'full': '9999px',
+       'large': '12px',
      }
    }
  }

Variants

默認情況下, 只有 響應式 的 border radius 變化模式 (variants) 會產生。

tailwind.config.jsvariants 區塊中變更 borderRadius 屬性來決定有哪些變化模式會生成。

舉個例子來說,這個設定將會生成 響應式 和 hover 的變化模式。

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       borderRadius: ['responsive', 'hover'],
      }
    }
  }

Disabling

如果你不打算在專案中使用 border radius 功能,可以在你的設定檔裡的 corePlugins 屬性中將 borderRadius 設定為 false 來停用功能:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     borderRadius: false,
    }
  }
