how to implement a layout that adapts to the width automatically with pure css?
for example: in div, the minimum width of a sub-div is 200 and the maximum width is 250. when the browser window becomes wider, the number of each row automatically increases, and all the sub-div of each line are full of width, and the edges cannot be left blank.
can it be achieved with flex or grid? (it is best not to use media query)
