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 keep things simple, so you can focus on what matters to you. Friendly people answer your questions quickly, by phone, chat or email. Every piece is made in small batches from materials we test ourselves. Every detail is handled by people who care about getting it right.
