It is sometimes useful to be able to add large amounts of content to a fixed area of the screen.
For example, suppose we want to set a div to have a height of 100px and a width of 200px, so that any text in the div must appear in that box.
The CSS overflow property will keep the box dimensions of the box
fixed.
The CSS property is overflow:scroll; or overflow:auto;
<div style='width:200px;height:80px;border:solid 1px red;overflow:scroll;'>
Note scrollbars are added automatically so we can view all information.
