However, if this is your reason for using an iframe,
you??™re better off replacing it with a div and using CSS to control the overflow. If you use
this method, the content will remain part of the web page, which is better for accessibility
and site maintenance.
To do this, create a div with a unique class value:
[content...]
Then style it in CSS??”the rule provides the div??™s dimensions and determines how the div??™s
overflow works:
.scrollableContent {
width: 200px;
height: 200px;
overflow: auto;
}
When overflow is set to auto, scroll bars only appear when the content is too large for the
set dimensions of the div. Other available values are hidden (display no scroll bars),
scroll (permanently display both scroll bars), and visible (render content outside of the
defined box area). Adding some padding, especially at the right-hand side of the scrollable
content box, helps improve the area aesthetically, ensuring that content doesn??™t hug the
scroll bar.
.scrollableContent {
width: 200px;
height: 200px;
overflow: auto;
padding: 0 10px 0 0;
}
Note that by also using PHP includes (see PHP Solutions, by David Powers, for more on
those), you can even make scrollable content separate from the main web page, thereby
emulating another aspect of an iframe, but without resorting to using frames at all.
