| |
| So: |
| |
| 60% : left |
| + |
| 0px : margin-left |
| + |
| 25px : border-left-width |
| + |
| 0px : padding-left |
| + |
| auto : width (set to shrink-to-fit) |
| + |
| 0px : padding-right |
| + |
| 75px : border-right-width |
| + |
| 0px : margin-right |
| + |
| solve : right |
| ==================== |
| 500px : width of containing block (width of Initial Containing Block) |
| |
| becomes |
| |
| 300px : left (60% of 500px == 300px) |
| + |
| 0px : margin-left |
| + |
| 25px : border-left-width |
| + |
| 0px : padding-left |
| + |
| 0px : width (shrink-to-fit) |
| + |
| 0px : padding-right |
| + |
| 75px : border-right-width |
| + |
| 0px : margin-right |
| + |
| solve : right |
| ==================== |
| 500px : width of containing block (width of Initial Containing Block) |
| |
| so used right offset value must be 100px. |
