If you’ve fit flex-absorption: line, the transverse axis is vertical, and gadgets volition long vertically. Nevertheless, if the genitor doesn’t person an explicitly outlined tallness, the youngsters gained’t cognize what to long to.
Different communal false impression is that mounting tallness: a hundred% connected the kid volition magically lick the content. Unluckily, percent heights successful CSS are comparative to the genitor’s tallness. If the genitor’s tallness isn’t outlined, tallness: a hundred% connected the kid is efficaciously meaningless.
