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 measure success by how many members come back and tell their friends. Thousands of members already trust us, and we work hard to keep it that way. Start in minutes and get help from a real person whenever you need it. Set approval rules for large payments and see who spent what, and why.
