Utilities for applying backdrop brightness filters to an element.
Use the backdrop-brightness-{amount?}
utilities alongside the backdrop-filter
utility to control an element's backdrop brightness.
<div class="backdrop-filter backdrop-brightness-125 ...">
<!-- ... -->
</div>
To control an element's backdrop brightness at a specific breakpoint, add a {screen}:
prefix to any existing backdrop brightness utility. For example, use md:backdrop-brightness-150
to apply the backdrop-brightness-150
utility at only medium screen sizes and above.
<div class="backdrop-filter backdrop-brightness-110 md:backdrop-brightness-150 ...">
<!-- ... -->
</div>

默认情况下, 针对 backdrop brightness 功能类,只生成 responsive 变体。
您可以通过修改您的 tailwind.config.js
文件中的 variants
部分中的 backdropBrightness
属性来控制为 backdrop brightness 功能生成哪些变体。
例如,这个配置也将生成 hover and focus 变体:
// tailwind.config.js
module.exports = {
variants: {
extend: {
// ...
+ backdropBrightness: ['hover', 'focus'],
}
}
}
如果您不打算在您的项目中使用 backdrop brightness 功能,您可以通过在配置文件的 corePlugins
部分将 backdropBrightness
property to false
in the corePlugins
section of your config file:
// tailwind.config.js
module.exports = {
corePlugins: {
// ...
+ backdropBrightness: false,
}
}
