| So: |
| |
| auto : left |
| + |
| 0px : margin-left |
| + |
| 35px : border-left-width |
| + |
| 0px : padding-left |
| + |
| 50px : width |
| + |
| 0px : padding-right |
| + |
| 15px : border-right-width |
| + |
| 0px : margin-right |
| + |
| 80% : right |
| ==================== |
| 500px : width of containing block (width of Initial Containing Block) |
| |
| becomes |
| |
| (solve) : left |
| + |
| 0px : margin-left |
| + |
| 35px : border-left-width |
| + |
| 0px : padding-left |
| + |
| 50px : width |
| + |
| 0px : padding-right |
| + |
| 15px : border-right-width |
| + |
| 0px : margin-right |
| + |
| 400px : right (80% of 500px == 400px) |
| ==================== |
| 500px : width of containing block (width of Initial Containing Block) |
| |
| so used left offset value must be 0px . |
