Utilities for applying grayscale filters to an element.
Use the grayscale
and grayscale-0
utilities alongside the filter
utility to whether an element should be rendered as grayscale or in full color.
<div class="filter grayscale ...">
<!-- ... -->
</div>
To control an element’s grayscale filter at a specific breakpoint, add a {screen}:
prefix to any existing grayscale utility. For example, use md:grayscale-0
to apply the grayscale-0
utility at only medium screen sizes and above.
<div class="filter grayscale md:grayscale-0 ...">
<!-- ... -->
</div>

You can customize which grayscale
utilities are generated using the grayscale
key in the theme
section of your tailwind.config.js
file.
// tailwind.config.js
module.exports = {
theme: {
+ extend: {
+ grayscale: {
+ 50: '50%',
+ }
+ }
}
}
Learn more about customizing the default theme in the theme customization documentation.
默認情況下, 只有 響應式 的 grayscale 變化模式 (variants) 會產生。
在 tailwind.config.js
的 variants
區塊中變更 grayscale
屬性來決定有哪些變化模式會生成。
舉個例子來說,這個設定將會生成 響應式 和 hover 的變化模式。
// tailwind.config.js
module.exports = {
variants: {
extend: {
// ...
+ grayscale: ['responsive', 'hover'],
}
}
}
如果你不打算在專案中使用 grayscale 功能,可以在你的設定檔裡的 corePlugins
屬性中將 grayscale
設定為 false
來停用功能:
// tailwind.config.js
module.exports = {
corePlugins: {
// ...
+ grayscale: false,
}
}
