Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The stroke-linecap
attribute is a presentation attribute defining the shape to be used at the end of open subpaths when they are stroked.
Note: As a presentation attribute stroke-linecap
can be used as a CSS property. See stroke-linecap
for more.
You can use this attribute with the following SVG elements:
Example
<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>

butt
The 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.
Example
<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
The 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.
Example
<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
The 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.
Example
<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" />
