CSS Overflow

The overflow property specifies the behavior that occurs when an element's content overflows (doesn't fit) the element's box.

Handling Overflowing Content

There may be a situation when the content of an element might be larger than the dimensions of the box itself. For example given width and height properties did not allow enough room to accommodate the content of the element.

CSS overflow property allowing you to specify whether to clip content, render scroll bars or display overflow content of a block-level element.

This property can take one of the following values: visible (default), hidden, scroll, and auto. CSS3 also defines the overflow-x and overflow-y properties which allow for independent control of the vertical and horizontal clipping.

  • div {
  •     width: 250px;
  •     height: 150px;
  •     overflow: scroll;
  • }
visible The default value. Content is not clipped; it will be rendered outside the element's box, and may thus overlap other content.
hidden Content that overflows the element's box is clipped and the rest of the content will be invisible.
scroll The overflowing content is clipped, just like hidden, but provides a scrolling mechanism to access the overflowed content.
auto If content overflows the element's box it will automatically provides the scrollbars to see the rest of the content, otherwise scrollbar will not appear.
