filter

示例

基础示例

使用 blur-xs 和 grayscale 等工具类为元素应用滤镜效果：

blur-xs

grayscale

组合效果

<img class="blur-xs" src="/img/mountains.jpg" /><img class="grayscale" src="/img/mountains.jpg" /><img class="blur-xs grayscale" src="/img/mountains.jpg" />

你可以组合使用以下滤镜工具类：模糊、亮度、对比度、投影、灰度、色相旋转、反相、饱和度 和 深褐色。

移除滤镜效果

使用 filter-none 工具类可以移除元素上应用的所有滤镜效果：

<img class="blur-md brightness-150 invert md:filter-none" src="/img/mountains.jpg" />

使用自定义值

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

<img class="filter-[url('filters.svg#filter-id')] ..." src="/img/mountains.jpg" />

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

<img class="filter-(--my-filter) ..." src="/img/mountains.jpg" />

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

悬停时应用

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

<img class="blur-sm hover:filter-none ..." src="/img/mountains.jpg" />

Learn more about using variants in the variants documentation.

响应式设计

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

<img class="blur-sm md:filter-none ..." src="/img/mountains.jpg" />
