I expect you'd keep two values for the margin: the fixed length, and the flex value. Collapsing two margins calc(2* + 100px) and calc(1* + 150px) would give you a collapsed margin of calc(2* + 150px). The 150px is always applied, and the flex value absorbs its quota of additional space when the available space is distributed. ~fantasai
