滤镜: drop-shadow()

示例

基础示例

使用像 drop-shadow-sm 和 drop-shadow-xl 的工具类为元素添加阴影:

<svg class="drop-shadow-md ...">
  <!-- ... -->
</svg>
<svg class="drop-shadow-lg ...">
  <!-- ... -->
</svg>
<svg class="drop-shadow-xl ...">
  <!-- ... -->
</svg>

这对于将阴影应用于不规则形状（如文本和 SVG 元素）非常有用。如果要将阴影应用于规则元素，您可能希望使用 盒子阴影 。

使用自定义值

Use the drop-shadow-[<value>] syntax to set the 投影阴影 based on a completely custom value:

<svg class="drop-shadow-[0_35px_35px_rgba(0,0,0,0.25)] ...">
  <!-- ... -->
</svg>

For CSS variables, you can also use the drop-shadow-(<custom-property>) syntax:

<svg class="drop-shadow-(--my-drop-shadow) ...">
  <!-- ... -->
</svg>

This is just a shorthand for drop-shadow-[var(<custom-property>)] that adds the var() function for you automatically.

响应式设计

Prefix a filter: drop-shadow() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<svg class="drop-shadow-md md:drop-shadow-xl ...">
  <!-- ... -->
</svg>

Learn more about using variants in the variants documentation.

自定义主题

Use the --drop-shadow-* theme variables to customize the 投影阴影 utilities in your project:

@theme {
  --drop-shadow-3xl: 0 35px 35px rgba(0, 0, 0, 0.25); 
}

Now the drop-shadow-3xl utility can be used in your markup:

<svg class="drop-shadow-3xl">
  <!-- ... -->
</svg>
