	<meta name="assert" content="The clip-path property allows specifying
	basic shapes and reference boxes. This test checks the usage of the correct
	reference box 'border-box' for the polygon() function by mixing percentage
	and absolute values as coordinates. On sucess you should see a green
	vertical stripe next to a lime green vertical stripe. Both should be of equal
	size.">

div {
	width: 50px;
	height: 50px;
	background-color: green;
	padding: 25px;
	margin: 25px;

	<p>The test passes if you see a green vertical stripe next to a lime green vertical stripe, both stripes should be of equal size and there should be no red.</p>
