| <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> |

| <meta content="" name="flags"> |
| <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"> |
| 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. |
