backdrop-filter: blur()

示例

基本示例

使用诸如 backdrop-blur-sm 和 backdrop-blur-lg 的工具类来控制元素的背景模糊：

backdrop-blur-none

backdrop-blur-sm

backdrop-blur-md

<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-none ..."></div>
</div>
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-sm ..."></div>
</div>
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-md ..."></div>
</div>

使用自定义值

Use the backdrop-blur-[<value>] syntax to set the 背景模糊 based on a completely custom value:

<div class="backdrop-blur-[2px] ...">
  <!-- ... -->
</div>

For CSS variables, you can also use the backdrop-blur-(<custom-property>) syntax:

<div class="backdrop-blur-(--my-backdrop-blur) ...">
  <!-- ... -->
</div>

This is just a shorthand for backdrop-blur-[var(<custom-property>)] that adds the var() function for you automatically.

响应式设计

Prefix a backdrop-filter: blur() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="backdrop-blur-none md:backdrop-blur-lg ...">
  <!-- ... -->
</div>

Learn more about using variants in the variants documentation.

自定义主题

Use the --blur-* theme variables to customize the 背景模糊 utilities in your project:

@theme {
  --blur-2xs: 2px; 
}

Now the backdrop-blur-2xs utility can be used in your markup:

<div class="backdrop-blur-2xs">
  <!-- ... -->
</div>
