Two basic options. Really only one good one. You can use an iframe to display another page on your page. But iframe is non-standard in its implementation and is being phased out, it is the 'bad' option, but still workable in some cases. The good option is to use a div element with set width and height and overflow auto, ex:
HTML Code:
<div style="width:250px;height:175px;overflow:auto;">
If your content in here is no wider than 250px or can wrap to 250px width,
when it's height exceeds 175px, a vertical scrollbar will appear to aid in
viewing the portion of the content not that's not at first visible.<br> <br>

</div>
