stroke-linecap
stroke-linecap
属性是用于定义描边(stroke)在描边开放子路径(open subpaths)末端形状的表示属性。
注意: 作为一个表示属性,stroke-linecap
也有一个对应的 CSS 属性:stroke-linecap
。当两者都被指定时,CSS 属性具有更高的优先级。
你可以将此属性与以下 SVG 元素一起使用
示例
html
<svg viewBox="0 0 6 6" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the (default) "butt" value -->
<line x1="1" y1="1" x2="5" y2="1" stroke="black" stroke-linecap="butt" />
<!-- Effect of the "round" value -->
<line x1="1" y1="3" x2="5" y2="3" stroke="black" stroke-linecap="round" />
<!-- Effect of the "square" value -->
<line x1="1" y1="5" x2="5" y2="5" stroke="black" stroke-linecap="square" />
<!--
the following pink lines highlight the
position of the path for each stroke
-->
<path d="M1,1 h4 M1,3 h4 M1,5 h4" stroke="pink" stroke-width="0.025" />
</svg>
用法说明

butt(平头)
butt
值表示描边在每个子路径的两个端点处不会延伸。对于零长度的子路径,该路径将完全不被渲染。
示例
html
<svg viewBox="0 0 6 4" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "butt" value -->
<path d="M1,1 h4" stroke="black" stroke-linecap="butt" />
<!-- Effect of the "butt" value on a zero length path -->
<path d="M3,3 h0" stroke="black" stroke-linecap="butt" />
<!--
the following pink lines highlight the
position of the path for each stroke
-->
<path d="M1,1 h4" stroke="pink" stroke-width="0.025" />
<circle cx="1" cy="1" r="0.05" fill="pink" />
<circle cx="5" cy="1" r="0.05" fill="pink" />
<circle cx="3" cy="3" r="0.05" fill="pink" />
</svg>
round
round
值表示在每个子路径的末端,描边将向外延伸一个半圆形,其直径等于描边宽度。对于零长度的子路径,描边由一个以子路径点为中心的完整圆形组成。
示例
html
<svg viewBox="0 0 6 4" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "round" value -->
<path d="M1,1 h4" stroke="black" stroke-linecap="round" />
<!-- Effect of the "round" value on a zero length path -->
<path d="M3,3 h0" stroke="black" stroke-linecap="round" />
<!--
the following pink lines highlight the
position of the path for each stroke
-->
<path d="M1,1 h4" stroke="pink" stroke-width="0.025" />
<circle cx="1" cy="1" r="0.05" fill="pink" />
<circle cx="5" cy="1" r="0.05" fill="pink" />
<circle cx="3" cy="3" r="0.05" fill="pink" />
</svg>
square
square
值表示在每个子路径的末端,描边将向外延伸一个矩形,该矩形的宽度等于描边宽度的一半,高度等于描边宽度。对于零长度的子路径,描边由一个以子路径点为中心的、宽度等于描边宽度的正方形组成。
示例
html
<svg viewBox="0 0 6 4" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "square" value -->
<path d="M1,1 h4" stroke="black" stroke-linecap="square" />
<!-- Effect of the "square" value on a zero length path -->
<path d="M3,3 h0" stroke="black" stroke-linecap="square" />
<!--
the following pink lines highlight the
position of the path for each stroke
-->
<path d="M1,1 h4" stroke="pink" stroke-width="0.025" />
<circle cx="1" cy="1" r="0.05" fill="pink" />
<circle cx="5" cy="1" r="0.05" fill="pink" />
<circle cx="3" cy="3" r="0.05" fill="pink" />
