stroke-linejoin
The stroke-linejoin
attribute is a presentation attribute defining the shape to be used at the corners of paths when they are stroked.
Note: As a presentation attribute stroke-linejoin
can be used as a CSS property.
You can use this attribute with the following SVG elements:

arcs
Note: The arcs
value as been introduced in SVG2 and it isn't widely supported yet, see Browser compatibility below for details.
The arcs
value indicates that an arcs corner is to be used to join path segments. The arcs shape is formed by extending the outer edges of the stroke at the join point with arcs that have the same curvature as the outer edges at the join point.
html
<svg viewBox="0 0 6 6" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "arcs" value -->
<path
d="M1,5 a2,2 0,0,0 2,-3 a3,3 0 0 1 2,3"
stroke="black"
fill="none"
stroke-linejoin="arcs" />
<!--

<g id="p">

<circle cx="3" cy="2" r="0.05" fill="pink" />
<circle cx="5" cy="5" r="0.05" fill="pink" />
</g>
</svg>
bevel
The bevel
value indicates that a bevelled corner is to be used to join path segments.
html
<svg viewBox="0 0 6 6" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "bevel" value -->
<path
d="M1,5 l2,-3 l2,3"
stroke="black"
fill="none"
stroke-linejoin="bevel" />
<!--
the following pink lines highlight the
position of the path for each stroke
-->
<g id="p">
<path d="M1,5 l2,-3 l2,3" stroke="pink" fill="none" stroke-width="0.025" />
<circle cx="1" cy="5" r="0.05" fill="pink" />
<circle cx="3" cy="2" r="0.05" fill="pink" />
<circle cx="5" cy="5" r="0.05" fill="pink" />
</g>
</svg>
miter
The miter
value indicates that a sharp corner is to be used to join path segments. The corner is formed by extending the outer edges of the stroke at the tangents of the path segments until they intersect.
Note: If the stroke-miterlimit
is exceeded, the line join falls back to bevel
.
html
<svg viewBox="0 -1 10 7" xmlns="http://www.w3.org/2000/svg">
<!-- Effect of the "miter" value -->
<path
d="M1,5 l2,-3 l2,3"
stroke="black"
fill="none"
stroke-linejoin="miter" />
<!-- Effect of the "miter" value on a sharp angle
where de default miter limit is exceeded -->
<path
d="M7,5 l0.75,-3 l0.75,3"
stroke="black"
fill="none"
stroke-linejoin="miter" />
<!-- the following red dotted line show where
the miter value falls back to the bevel value -->
<path
d="M0,0 h10"
stroke="red"
stroke-dasharray="0.05"
stroke-width="0.025" />
<!-- the following pink lines highlight the position of the path for each stroke -->
<g>
<path d="M1,5 l2,-3 l2,3" stroke="pink" fill="none" stroke-width="0.025" />
<circle cx="1" cy="5" r="0.05" fill="pink" />
<circle cx="3" cy="2" r="0.05" fill="pink" />
<circle cx="5" cy="5" r="0.05" fill="pink" />
<path

stroke="pink"
fill="none"
stroke-width="0.025" />
<circle cx="7" cy="5" r="0.05" fill="pink" />
<circle cx="7.75" cy="2" r="0.05" fill="pink" />
<circle cx="8.5" cy="5" r="0.05" fill="pink" />
</g>
</svg>
miter-clip
Note: the miter-clip
value as been introduced in SVG2 and it isn't widely supported yet, see Browser compatibility below for details.
The miter-clip
value indicates that a sharp corner is to be used to join path segments. The corner is formed by extending the outer edges of the stroke at the tangents of the path segments until they intersect.
If the stroke-miterlimit
is exceeded, the miter is clipped at a distance equal to half the stroke-miterlimit
value multiplied by the stroke width from the intersection of the path segments. This provides a better rendering than miter
on very sharp join or in case of an animation.

<!-- Effect of the "miter-clip" value -->
<path

round
The round
value indicates that a round corner is to be used to join path segments.
