SVG Polygons in HTML

Here's a quick tutorial that will teach you how to create a polygon with HTML's svg and polygon tags.

A polygon is a connected series of line segments creating a closed, solid path. Here's an illustration of what we'll be creating:

<svg xmlns="http://www.w3.org/2000/svg"
	viewBox="0 0 1000 200">

	<polygon points="250,100 500,25 750,150 575,125 500,175 475,75"
		stroke="#e89a3e"
		stroke-width="4"
		fill="#cf8630"
		opacity="1.0" />
</svg>

The Attributes

Here are the attributes used to define our polygon:

• points: A list of points, each containing an x and y coordinate, and separated by a space or end-of-line character. The first and last points defined will connect to close the polygon.
• stroke: The color of the border line. This value can be defined either by specifying a hexadecimal color code as we did above or by using a valid color name.
• stroke-width: The width of the border line output to the screen, relative to the size of the viewbox.
• fill: The fill color can also be defined as a hexadecimal color code or color name and will fill the polygon with the color specified. Specifying a value of none will keep the polygon fill color transparent.
• opacity: Determines if the polygon will have any transparency. Valid decimal values can be between 0.0 (invisible) and 1.0 (fully visible). A value of 0.5 would give the polygon 50% transparency.
