滤镜
用于将背景灰度滤镜应用于元素的工具。
¥Basic usage
¥Making an element grayscale
使用 backdrop-grayscale
和 backdrop-grayscale-0
工具来控制元素的背景应该渲染为灰度还是全彩色。
¥Use the backdrop-grayscale
and backdrop-grayscale-0
utilities to control whether an element’s backdrop should be rendered as grayscale or in full color.
backdrop-grayscale-0
backdrop-grayscale
<div class="backdrop-grayscale-0 bg-white/30 ...">
<!-- ... -->
</div>
<div class="backdrop-grayscale bg-white/30 ...">
<!-- ... -->
</div>
¥Removing backdrop filters
To remove all of the backdrop filters on an element at once, use the backdrop-filter-none
utility:
<div class="backdrop-blur-md backdrop-grayscale md:backdrop-filter-none">
<!-- ... -->
</div>
This can be useful when you want to remove backdrop 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:backdrop-grayscale-0
to only apply the backdrop-grayscale-0
utility on hover.
<div class="backdrop-grayscale hover:backdrop-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:backdrop-grayscale-0
to apply the backdrop-grayscale-0
utility at only medium screen sizes and above.
<div class="backdrop-grayscale md:backdrop-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 backdrop-grayscale
工具。你可以通过编辑 tailwind.config.js
文件中的 theme.backdropGrayscale
或 theme.extend.backdropGrayscale
来自定义这些值。
¥By default, Tailwind includes a handful of general purpose backdrop-grayscale
utilities. You can customize these values by editing theme.backdropGrayscale
or theme.extend.backdropGrayscale
in your tailwind.config.js
file.
module.exports = {
theme: {
extend: {
backdropGrayscale: {
50: '.5',
}
}
}
}

¥Learn more about customizing the default theme in the theme customization documentation.
¥Arbitrary values
If you need to use a one-off backdrop-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="backdrop-grayscale-[.5]">
<!-- ... -->
</div>
