<title>CSS Backgrounds and Borders Test: border-image-slice - &lt;percentage&gt;</title>
<link rel="author" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/" />
<link rel="help" href="http://www.w3.org/TR/css3-background/#the-border-image-slice" title="6.2. Image Slicing: the 'border-image-slice' property" />
<link rel="match" href="../reference/ref-filled-green-100px-square.xht" />
<meta name="flags" content="image" />
<meta name="assert" content="Percentage values for 'border-image-slice' are relative to the size of the image: the width of the image for the horizontal (left and right) offsets, the height for vertical (top and bottom) offsets. 'border-image-slice' specifies inward offsets from the top, right, bottom, and left edges (in that order) of the image. In this test, the image serving as 'border-image-source' is a 100px by 100px image which has 5px of green at the top, 10px of green on the right, 15px of green at the bottom and 20px of green at the left; the remaining center (which has a width of 70px and a height of 80px) is all red." />
