Create Scrolling Content Using the Content Editor
If you have a lot of content you want to display but really only have a small area on the site to display it you could make use of this useless trick.
Let’s assume we have a 200×200 pixel area on our screen but we have a page of text that has to fit in there.
Drag the content editor web part into the zone in the area you wish to display it.
Edit the web part properties and set the height of the web part to 200 pixels.
By default the web parts will scroll any additional content which flows outside of the calculated area (overflow) of the web part giving you scrollable content.
