When you use flex by default the height are same , if you change the align items values to like center, start, end the height may be changed , also make sure there is not extra padding or margin or any fixed height on the boxes , Hope it helps.

@Yehan20 I have learned this concept well, be careful when I use align-items, this is what caused the problem of inequality of boxes, thank you Yehan very much for your intervention
