示例
基本示例
使用 mask-center、mask-right 和 mask-left-top 等工具类来控制元素遮罩图像的位置：
mask-top-left
mask-top
mask-top-right
mask-left
mask-center
mask-right
mask-bottom-left
mask-bottom
mask-bottom-right
<div class="mask-top-left mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-top mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-top-right mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-left mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-center mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-right mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-bottom-left mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-bottom mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-bottom-right mask-[url(/img/circle.png)] mask-size-[50%] bg-[url(/img/mountains.jpg)] ..."></div>
使用自定义值
使用 mask-position-[<value>] 语法，可以根据完全自定义的值来设置遮罩位置：
<div class="mask-position-[center_top_1rem] ...">
<!-- ... -->
</div>
对于 CSS 变量，您也可以使用 mask-position-(<custom-property>) 语法：
<div class="mask-position-(--my-mask-position) ...">
<!-- ... -->
</div>
这只是 mask-position-[var(<custom-property>)] 的简写形式，它会自动为您添加 var() 函数。
响应式设计
在 mask-position 工具类前加上 md: 等断点变体，以便仅在 中等 屏幕尺寸及以上应用该工具类：
<div class="mask-center md:mask-top ...">
<!-- ... -->
</div>
