边框半径

​基本用法

¥Basic usage

​圆角

¥Rounded corners

使用 rounded-sm、rounded 或 rounded-lg 等工具将不同的边框半径大小应用于元素。

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

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

​药丸按钮

¥Pill buttons

使用 rounded-full 工具创建药丸按钮。

¥Use the rounded-full utility to create pill buttons.

<button class="rounded-full ...">Save Changes</button>

​没有四舍五入

¥No rounding

使用 rounded-none 从元素中删除现有的边框半径。

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

<button class="rounded-none ...">Save Changes</button>

这最常用于删除在较小断点处应用的边框半径。

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

​分别圆边

¥Rounding sides separately

使用 rounded-t-*、rounded-r-*、rounded-b-* 和 rounded-l-* 工具仅舍入元素的一侧。

¥Use the rounded-t-*, rounded-r-*, rounded-b-*, and rounded-l-* utilities to only round one side of an element.

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

​分别圆角

¥Rounding corners separately

使用 rounded-tl-*、rounded-tr-*、rounded-br-* 和 rounded-bl-* 工具仅圆化元素的一个角。

¥Use the rounded-tl-*, rounded-tr-*, rounded-br-*, and rounded-bl-* utilities to only round one corner of an element.

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

​使用逻辑属性

使用 rounded-s-*、rounded-e-*、rounded-ss-*、rounded-se-*、rounded-es-* 和 rounded-ee-* 工具使用 逻辑属性 设置边框半径，该半径根据文本方向映射到相应的角。

¥Use the rounded-s-*, rounded-e-*, rounded-ss-*, rounded-se-*, rounded-es-*, and rounded-ee-* utilities to set the border radius using logical properties, which map to the appropriate corners based on the text direction.

<div dir="ltr">
  <div class="rounded-s-lg ..."></div>
<div>

<div dir="rtl">
  <div class="rounded-s-lg ..."></div>
<div>

以下是所有可用的边框颜色逻辑属性工具及其在 LTR 和 RTL 模式下的等效物理属性。

¥Here are all the available border color logical property utilities and their physical property equivalents in both LTR and RTL modes.

要获得更多控制，你还可以使用 LTR 和 RTL 修饰符 根据当前文本方向有条件地应用特定样式。

¥For more control, you can also use the LTR and RTL modifiers to conditionally apply specific styles depending on the current text direction.

​有条件地应用

​悬停、聚焦和其他状态

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

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

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. 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>

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

​使用自定义值

¥Using custom values

​自定义主题

¥Customizing your theme

默认情况下，Tailwind 提供五个边框半径大小工具。你可以通过编辑 Tailwind 配置的 theme.borderRadius 部分来更改、添加或删除它们。

¥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.

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

在 主题定制 文档中了解有关自定义默认主题的更多信息。

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

​任意值

¥Arbitrary values

If you need to use a one-off border-radius 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.

<div class="rounded-[12px]">
  <!-- ... -->
</div>

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