| <p> Bug <a href="http://webkit.org/b/34875">34875</a>: offsetLeft broken within CSS3 columns </p> |
| <p>There should not be any red spans visible.</p> |
| <p> |
| This test checks that offsetLeft and offsetTop return correct values when used |
| on elements contained in multiple columns. We put a number of red spans (of |
| arbitrary size) in a multi-column div. The script at the end creates an |
| identically sized green span for each of the red spans, and places it at the |
| offsetLeft and offsetTop of the red span, using absolute position. This ensures |
| that the green span completely covers the red span. |
