基本用法

¥Basic usage

圆角

¥Rounded corners

使用 rounded-smroundedrounded-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.

rounded

rounded-md

rounded-lg

rounded-full

<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.

rounded-full

<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.

rounded-none

<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-*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.

rounded-t-lg

rounded-r-lg

rounded-b-lg

rounded-l-lg

<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-*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.

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>

使用逻辑属性

使用 rounded-s-*rounded-e-*rounded-ss-*rounded-se-*rounded-es-*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.

Left-to-right

Right-to-left

<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.

左到右右到左
rounded-s-*rounded-l-*rounded-r-*
rounded-e-*rounded-r-*rounded-l-*
rounded-ss-*rounded-tl-*rounded-tr-*
rounded-se-*rounded-tr-*rounded-tl-*
rounded-es-*rounded-bl-*rounded-br-*
rounded-ee-*rounded-br-*rounded-bl-*

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 允许你使用变体修饰符在不同状态下有条件地应用工具类。例如,使用hover:rounded-lg 仅在 hover 时应用 rounded-lg 工具。

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

有关所有可用状态修饰符的完整列表,请查看悬停、聚焦、以及其他状态 文档。

断点和媒体查询

你还可以使用变体修饰符来定位媒体查询,例如响应式断点、暗黑模式、首选减少运动等。例如,使用 md:rounded-lg 仅在中等屏幕尺寸及以上时应用 rounded-lg 工具。

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

要了解更多信息,请查看有关 响应式设计暗黑模式、以及 其他媒体查询修饰符 的文档。


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.

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',
    }
  }
}

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

如果你需要使用一次性的 border-radius 值,而该值没有必要包含在你的主题中,请使用方括号动态生成属性,使用任意值。

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

任意值 文档中了解有关任意值支持的更多信息。
