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

Group tickets include a private meeting room for your team. Early bird tickets save you up to forty percent until the end of the month. More than eighty speakers share what they have learned the hard way. Friendly people answer your questions quickly, by phone, chat or email.
