backdrop-filter

示例

基础示例

使用 backdrop-blur-xs 和 backdrop-grayscale 等工具类来为元素的背景应用滤镜效果：

backdrop-blur-xs

backdrop-grayscale

组合效果

<div class="bg-[url(/img/mountains.jpg)] ...">  <div class="backdrop-blur-xs ..."></div></div><div class="bg-[url(/img/mountains.jpg)] ...">  <div class="backdrop-grayscale ..."></div></div><div class="bg-[url(/img/mountains.jpg)] ...">  <div class="backdrop-blur-xs backdrop-grayscale ..."></div></div>

你可以组合使用以下背景滤镜工具类：模糊、亮度、对比度、灰度、色相旋转、反相、不透明度、饱和度 和 深褐色。

移除滤镜效果

使用 backdrop-filter-none 工具类可以移除元素上应用的所有背景滤镜效果：

<div class="backdrop-blur-md backdrop-brightness-150 md:backdrop-filter-none"></div>

使用自定义值

Use the backdrop-filter-[<value>] syntax to set the 背景滤镜 based on a completely custom value:

<div class="backdrop-filter-[url('filters.svg#filter-id')] ...">  <!-- ... --></div>

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

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

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

悬停时应用

Prefix a backdrop-filter utility with a variant like hover:* to only apply the utility in that state:

<div class="backdrop-blur-sm hover:backdrop-filter-none ...">  <!-- ... --></div>

Learn more about using variants in the variants documentation.

响应式设计

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

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