CSS Overflow
CSS Layout - Overflow
The CSS overflow property controls what happens to content that is too big to fit into an area.
CSS Overflow
The overflow property specifies whether to clip content or to add scrollbars when the content of an element is too big to fit in a specified area.
The overflow property has the following values:
visible- Default. The overflow is not clipped. It renders outside the element's boxhidden- The overflow is clipped, and the rest of the content will be invisiblescroll- The overflow is clipped, but a scrollbar is added to see the rest of the contentauto- If overflow is clipped, a scrollbar should be added to see the rest of the content
Note: The overflow property only works for block elements with a specified height.
Note: In OS X Lion (on Mac), scrollbars are hidden by default and only shown when being used (even though "overflow:scroll" is set).
overflow: visible
By default, the overflow is visible, meaning that it is not clipped and it renders outside the element's box:
Example
div {
width: 200px;
height: 50px;
background-color: #eee;
overflow: visible;
}overflow: hidden
With the hidden value, the overflow is clipped, and the rest of the content is hidden:
Example
div {
overflow: hidden;
}overflow: scroll
Setting the value to scroll, the overflow is clipped and a scrollbar is added to scroll inside the box. Note that this will add a scrollbar both horizontally and vertically (even if you do not need it):
Example
div {
overflow: scroll;
}overflow: auto
The auto value is similar to scroll, only it add scrollbars when necessary:
Example
div {
overflow: auto;
}overflow-x and overflow-y
The overflow-x and overflow-y properties specifies whether to change the overflow of content just horizontally or vertically (or both):
overflow-x specifies what to do with the left/right edges of the content.overflow-y specifies what to do with the top/bottom edges of the content.
Example
div {
overflow-x: hidden; /* Hide horizontal scrollbar */
overflow-y: scroll; /* Add vertical scrollbar */
