Style Attributes

Here is a list of the most basic style attributes for SVG shape elements.

stroke

• Default is none
• Value is a CSS Color or none.

stroke-width

• Default is 1
• Value is a length value or percentage (e.g. 1%), relative to view port. .
• length value can be a CSS Unit, e.g. 2px (note, CSS length requires a unit), or just a integer. If just a integer, it means the unit of current coordinate.

stroke-dasharray

• Default is none
• Value should be a sequence of pairs of numbers, e.g. 10 2.
• If missing one, first value is used to fill last value.

stroke-linecap

• Default is butt
• Shape of ends of line.
• Possible values are: butt, round, square.

<svg width="100" height="100">
<line  x1="20" y1="50" x2="80" y2="50"
 style="stroke:blue; stroke-width:20;
stroke-linecap:butt" />
</svg>

stroke-linejoin

• Default is miter
• Shape of polygon bend.
• Possible values are: miter, round, bevel.

<svg width="200" height="200">
<polygon points="
0 0
150 150
150 100
0 100
"
style="stroke: blue; fill: yellow;
stroke-width:20;
stroke-linejoin:bevel
" />
</svg>

stroke-miterlimit

• Default is 4
• Value is a integer.
• max ratio of miter point to line thickness.

stroke-opacity

• Default is 1
• Value is 0 to 1.
• Value of 0 means transparent.

fill

stroke-opacity:.5;
fill-opacity:.5" />
<circle cx="70" cy="70" r="50"

fill-rule

• Default is nonzero
• Possible values are: nonzero, evenodd, inherit.
