<p class="text-purple-700 text-opacity-100 ...">The quick brown fox ...</p>
<p class="text-purple-700 text-opacity-75 ...">The quick brown fox ...</p>
<p class="text-purple-700 text-opacity-50 ...">The quick brown fox ...</p>
<p class="text-purple-700 text-opacity-25 ...">The quick brown fox ...</p>
<p class="text-purple-700 text-opacity-0 ...">The quick brown fox ...</p>Note that because these utilities are implemented using CSS custom properties, a .text-{color} utility must be present on the same element for them to work.
Don't try to use text opacity utilities on an inherited text color
<div class="text-black">
<div class="text-opacity-50">...</div>
</div>Do make sure to add a text color utility to the same element explicitly
<div class="text-black">
<div class="text-black text-opacity-50">...</div>
</div>To control an element’s text color opacity at a specific breakpoint, add a {screen}: prefix to any existing text color opacity utility. For example, use md:text-opacity-50 to apply the text-opacity-50 utility at only medium screen sizes and above.
<div class="text-blue-500 text-opacity-75 md:text-opacity-50">

To customize the opacity values for all opacity-related utilities at once, use the opacity section of your tailwind.config.js theme configuration:
// tailwind.config.js
module.exports = {
theme: {
extend: {
opacity: {
+ '10': '0.1',
+ '20': '0.2',
+ '95': '0.95',
}
}
}
}If you want to customize only the text opacity utilities, use the textOpacity section:
// tailwind.config.js
module.exports = {
theme: {
extend: {
textOpacity: {
+ '10': '0.1',
+ '20': '0.2',
+ '95': '0.95',
}
}
}
}Learn more about customizing the default theme in the theme customization documentation.
默認情況下, 只有 響應式、深色模式 (如果啟用)、group-hover、focus-within、hover 和 focus 的 text opacity 變化模式 (variants) 會產生。
在 tailwind.config.js 的 variants 區塊中變更 textOpacity 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 active 的變化模式。
// tailwind.config.js
module.exports = {
variants: {
extend: {
// ...
+ textOpacity: ['responsive', 'active'],
}
}
}如果你不打算在專案中使用 text opacity 功能，可以在你的設定檔裡的 corePlugins 屬性中將 textOpacity 設定為 false 來停用功能：
// tailwind.config.js
module.exports = {
corePlugins: {
// ...
+ textOpacity: false,
}
}
