CSS Function - polygon()

Quiz

The CSS function polygon() is one of the <basic-shape> data types and is used to create a polygon.

It requires the specification of one or more pairs of coordinates, each pair representing a vertex of the shape.

Possible values

<fill-rule> (optional) - An optional value that is either nonzero (default if omitted) or evenodd can be used to specify the fill rule.
<length-percentage> - Each vertex of the polygon is denoted by a pair of <lenght-percentage> values specifying the coordinates of the vertex with respect to the shape's reference box.

Syntax

polygon() = polygon( [<fill-rule>,]? [<shape-arg> <shape-arg>]# )
<shape-arg> = <length> | <percentage>

It returns a <basic-shape> value.

CSS polygon() - With Dimensions

The following example demonstrates working of polygon() with shape-outside property.

The polygonal shape, formed by specific coordinates, determines where the text wraps around the polygonal shape.

<html>
<head>
<style>
   #polygon-demo {
      float: left;
      width: 250px;  
      height: 150px;
      shape-outside: polygon(100px 20px, 200px 10px, 100px 250px);
   }
</style>
</head>
<body>
<div id="polygon-demo"></div>

CSS polygon() - Using clip-path

In the following example the shape-outside and clip-path properties are utilized to outline the polygon that determines how text is arranged within a container.

<html>
<head>
<style>
   .container {
      width: 500px;
      margin: 0 auto;
      padding: 20px;
      text-align: justify;
      color: blue;
      shape-outside: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
      clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
   }
</style>
</head>
<body>
