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

Every payment appears instantly, with receipts matched automatically. Set approval rules for large payments and see who spent what, and why. Start in minutes and get help from a real person whenever you need it. Thousands of members already trust us, and we work hard to keep it that way.
