<title>CSS Test: Double lines border style does not change border width</title>
<link rel="reviewer" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/" /> <!-- 2012-06-26 -->
<meta name="assert" content="The 'double' 'border-style' does not change the size of the border width. The sum of the two lines and the space need to equal the border width." />
<style type="text/css">
div
{
position: relative;
width: 1in;
}
#test
{
border-top-style: double;

background: blue;
height: 1in;
left: 1.1in;
