<title>CSS Test: Solving 'width: auto' of a block-level non-replaced element in normal flow with one other property set to an 'auto' value</title>
<link rel="author" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/" />
<link rel="help" title="10.3.3 Block-level, non-replaced elements in normal flow" href="http://www.w3.org/TR/CSS21/visudet.html#blockwidth" />
<meta content="If 'width' is set to 'auto', any other 'auto' values become '0' and the determination of 'width' proceeds from the following equality: 'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' = width of containing block" name="assert" />
<style type="text/css"><![CDATA[
div {height: 200px;}
div#containing-block
{
border-right: red solid 200px;
padding-right: 200px;
width: 0px;
}
div#child
{
border-right: green solid 200px;
margin-right: -400px;
}
/*
Calculation of used width for div#child:
margin-left : 0px (or auto)
+ border-left-width : 0px
+ padding-left : 0px
+ width : auto
+ padding-right : 0px
+ border-right-width : 200px
+ margin-right : -400px
====================================
width of containing block : 0px
Therefore 'width: auto' must be resolved as 'width: 200px'.
Therefore div#child's green border-right should overlap perfectly
div#containing-block's red border-right.
