Overflow
Overflow utilities control what happens when content is bigger than its box: overflow-auto scrolls when needed, overflow-hidden clips, overflow-visible lets content spill and overflow-scroll always shows scrollbars. overflow-x-* and overflow-y-* handle each axis separately, ideal for wide tables and side-scrolling rows.
1The four overflow values
overflow-auto, overflow-hidden, overflow-visible and overflow-scroll on boxes of fixed height.
