示例(Examples)

基本示例(Basic example)
¥Basic example
使用 brightness-50 和 brightness-100 等工具来控制元素的亮度：
¥Use utilities like brightness-50 and brightness-100 to control an element's brightness:
brightness-50
brightness-100
brightness-125
brightness-200
<img class="brightness-50 ..." src="/img/mountains.jpg" /><img class="brightness-100 ..." src="/img/mountains.jpg" /><img class="brightness-125 ..." src="/img/mountains.jpg" /><img class="brightness-200 ..." src="/img/mountains.jpg" />使用自定义值(Using a custom value)
¥Using a custom value
使用 brightness-[<value>] 语法 根据完全自定义的值设置 brightness：
<img class="brightness-[1.75] ..." src="/img/mountains.jpg" />对于 CSS 变量，还可以使用 brightness-(<custom-property>) 语法：
<img class="brightness-(--my-brightness) ..." src="/img/mountains.jpg" />这只是简写，用于 brightness-[var(<custom-property>)] 它会自动为你添加 var() 函数。
响应式设计(Responsive design)
¥Responsive design
在 filter: brightness() 工具前面使用断点变体如 md: 仅在 medium 屏幕尺寸及以上时应用工具：
<img class="brightness-110 md:brightness-150 ..." src="/img/mountains.jpg" />请参阅 变体文档 详细了解如何使用变体。
