| |
| 1st element gets 5/8 of space: 5/8 * 196px = 122.5px |
| 1st element gets 3/8 of space: 3/8 * 196px = 73.5px |

| different flex bases. |
| |
| Space-to-be-distributed = 200px - (33 + 1 + 1) - (13 + 1 + 1) = 150px |
| 1st element gets 2/5 of space: 33px + 2/5 * 150px = 93px |
| 1st element gets 3/5 of space: 13px + 3/5 * 150px = 103px |

| |
| Space-to-be-distributed = 200px - (150 + 1 + 1) - (100 + 1 + 1) = -54px |
| First element scaled flex ratio = 4 * 150 = 600 |
| Second element scaled flex ratio = 3 * 100 = 300 |
| * So, total flexibility is 600 + 300 = 900 |
| |
| 1st element gets 600/900 of space: 150 + 600/900 * -54 = 114px |
| 2nd element gets 300/900 of space: 100 + 300/900 * -54 = 82px |
