The first 3 lines boxes of 1st column box of div#inner will be rendered inside the 1st column box of div#outer but not its 2nd. Because 1st column box of div#outer is 6em wide while the div#inner multi-column element is 14em wide, this makes the first 3 line boxes (with the 'z' trios) of 2nd column box of div#inner clipped. Then, at this point, the div#inner multi-column element should be fragmented in order to continue to render the 5 empty line boxes it has into the 2nd column box of div#outer. Since those 5 line boxes are empty, we only see the extension it creates horizontally, which is 14em - 6em == 8em horizontally and 5 lines boxes == 5em tall Expected results: 0em 14em 22em v v v 0 ********************************************* * bla | * * bla | * * bla | * * bla | * 5 * bla | * 6 * orn |**************** 7 * orn | 8 * orn | ***************************** --> </body> </html>
