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

Start in minutes and get help from a real person whenever you need it. Honest advice comes first, even when it means waiting for the right home. Sellers get professional photos, floor plans and a marketing plan included. Our local agents know every street, school and coffee shop in the area.
