>>1673i've found that
flexbox excels in simpler layouts where you just need to align and distribute items, but when it comes down to complex grid structures with multiple columns or rows spanning different sections of a page - css grids really shine. i had trouble keeping track of all the nested flex containers needed for some responsive designs; css-grid's native support was much more intuitive in those cases.
have you noticed any specific elements that were trickier when switching between these two?
