滤镜

过滤器: 灰度()

用于将灰度滤镜应用于元素的工具类。

ClassStyles
grayscale
filter: grayscale(100%);
grayscale-<number>
filter: grayscale(<number>%);
grayscale-(<custom-property>)
filter: grayscale(var(<custom-property>));
grayscale-[<value>]
filter: grayscale(<value>);

示例

基本示例

使用 grayscalegrayscale-75 等工具类来控制应用于元素的灰度效果的程度:

grayscale-0

grayscale-25

grayscale-50

grayscale

<img class="grayscale-0 ..." src="/img/mountains.jpg" />
<img class="grayscale-25 ..." src="/img/mountains.jpg" />
<img class="grayscale-50 ..." src="/img/mountains.jpg" />
<img class="grayscale ..." src="/img/mountains.jpg" />

使用自定义值

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

<img class="grayscale-[0.5] ..." src="/img/mountains.jpg" />

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

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

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

响应式设计

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

<img class="grayscale md:grayscale-0 ..." src="/img/mountains.jpg" />

Learn more about using variants in the variants documentation.
