| <p>Test adding ::before and ::after pseudo elements that are spanners. The DOM element contains |
| something, and is also preceded and followed by content, which means that what used to be one column |
| row needs to be split into three.</p> |
| <p>There should be five rectangles with identical sizes below. The first, third and fifth |
| one should be blue with nothing inside. The second and fourth one should be yellow with some |
| dots inside.</p> |
| <div style="-webkit-columns:4; line-height:50px; background:blue;"> |

| <span id="elm"> </span> |
