HTML Scroll Box
When its contents are too big to fit inside the box, an HTML scroll box expands its scroll bars. How is the box made? A standard HTML element, like the div element, is used to create the box. Next, you apply the CSS overflow property to the div to make the box scroll.
However, if you don't want to, you don't have to worry about the technical details. The HTML scroll box code below is easy to copy and paste. Naturally, you can alter the values to fit your needs (e.g., scroll box size, color, etc.).
Simple Scroll Box in HTML
<div style="height:120px;width:120px;border:1px solid #ccc;font:16px/26px Georgia, Garamond, Serif;overflow:auto;">
As you can see, once there's enough text in this box, the box will grow scroll bars... that's why we call it a scroll box! You could also place an image into the scroll box.
