滤镜
用于将灰度滤镜应用于元素的工具。
¥Basic usage
¥Making an element grayscale
使用 grayscale
和 grayscale-0
工具来控制元素是应渲染为灰度还是全彩色。
¥Use the grayscale
and grayscale-0
utilities to control whether an element should be rendered as grayscale or in full color.
grayscale-0
grayscale
<div class="grayscale-0 ...">
<!-- ... -->
</div>
<div class="grayscale ...">
<!-- ... -->
</div>
¥Removing filters
To remove all of the filters on an element at once, use the filter-none
utility:
<div class="blur-md invert grayscale md:filter-none">
<!-- ... -->
</div>
This can be useful when you want to remove filters conditionally, such as on hover or at a particular breakpoint.
Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:grayscale-0
to only apply the grayscale-0
utility on hover.
<div class="grayscale hover:grayscale-0">
<!-- ... -->
</div>
For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.
You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:grayscale-0
to apply the grayscale-0
utility at only medium screen sizes and above.
<div class="grayscale md:grayscale-0">
<!-- ... -->
</div>
To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.
¥Using custom values
¥Customizing your theme
默认情况下,Tailwind 包含一些通用 grayscale
工具。你可以通过编辑 tailwind.config.js
文件中的 theme.grayscale
或 theme.extend.grayscale
来自定义这些值。
¥By default, Tailwind includes a handful of general purpose grayscale
utilities. You can customize these values by editing theme.grayscale
or theme.extend.grayscale
in your tailwind.config.js
file.
module.exports = {
theme: {
extend: {
grayscale: {
50: '50%',
}
}
}
}

¥Learn more about customizing the default theme in the theme customization documentation.
¥Arbitrary values
If you need to use a one-off grayscale
value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.
<div class="grayscale-[50%]">
<!-- ... -->
</div>
