The answer is here: https://drafts.csswg.org/css-flexbox/#item-margins [quote] Percentage margins and paddings on flex items are always resolved against their respective dimensions; unlike blocks, they do not always resolve against the inline dimension of their containing block. [/quote] given that the height of your flex items (<figure>) is auto, the vertical padding computes to 0. PS - don’t forget to add the -webkit- prefixed properties / values for Safari.
