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

We find the best price, and if you see it cheaper we match it. Travel insurance and car rental can be added in a single click. Clear prices, honest advice and no surprises along the way. We find the best price, and if you see it cheaper we match it.
