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

Family rooms, adults-only retreats and pet-friendly stays in one search. Clear prices, honest advice and no surprises along the way. Every hotel on our list is visited and reviewed by our own travel team. We find the best price, and if you see it cheaper we match it.
