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.

overflow-auto

Our team has done this many times, so you never have to guess. Every detail is handled by people who care about getting it right. Every dish is cooked to order, so tell us if you would like anything changed. We keep things simple, so you can focus on what matters to you.
