stroke-width 表现属性定义了应用于图形的外轮廓的宽度。

你可以将此属性与以下 SVG 元素一起使用：

示例

html
<svg viewBox="0 0 30 10" xmlns="http://www.w3.org/2000/svg">
  <!-- 默认外轮廓宽度为 1 -->
  <circle cx="5" cy="5" r="3" stroke="green" />

  <!-- 使用数值设置外轮廓宽度 -->
  <circle cx="15" cy="5" r="3" stroke="green" stroke-width="3" />

  <!-- 使用百分数设置外轮廓宽度 -->
  <circle cx="25" cy="5" r="3" stroke="green" stroke-width="2%" />
</svg>

使用说明

值 <length> | <percentage>
默认值 1px

备注： 百分数值始终以标准化 viewBox 的对角线长度的百分比计算。
