Math written in prose tends to be confusing, so maybe I am missing something, but I think there is an error in the algorithm section "9.7. Resolving Flexible Lengths" "If the free space is negative For every item on the line, multiply its flex shrink ratio by its outer flex base size, and note this as its scaled flex shrink ratio. Find the ratio of the item's scaled flex shrink ratio to the sum of the scaled flex shrink ratios of all items on the line. Set the item's main size to its flex base size minus a fraction of the free space proportional to the ratio." If the free space is negative, a fraction of the free space proportional to the ratio is negative too, since the ratio is positive. So flex base size minus some negative thing would give a main size larger than the base size, which can't be right when you have negative free space. So, unless I missed something somewhere, I suggest replacing the last sentence of the paragraph quoted with either of the following 2 proposals: "Set the item's main size to its flex base size minus a fraction of the absolute value of the free space proportional to the ratio." or "Set the item's main size to its flex base size plus a fraction of the free space proportional to the ratio." - Florian
