范例

html,body,svg { height:100% }

								

<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>

								

用法注意事项

butt

butt value indicates that the stroke for each subpath does not extend beyond its two endpoints. On a zero length subpath, the path will not be rendered at all.

范例

html,body,svg { height:100% }

								

<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 value indicates that at the end of each subpath the stroke will be extended by a half circle with a diameter equal to the stroke width. On a zero length subpath, the stroke consists of a full circle centered at the subpath's point.

  <!-- 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

  <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 value indicates that at the end of each subpath the stroke will be extended by a rectangle with a width equal to half the width of the stroke and a height equal to the width of the stroke. On a zero length subpath, the stroke consists of a square with its width equal to the stroke width, centered at the subpath's point.

        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" />
