Say you have a lot of text that you want to put into a scrollbox. Add a CSS rule (class). Go to Box under Catergory and define the height and width. Go to Positioning and select scroll. Go to the split screen and apply the <div> tags around the text you want to put in the scroll box. The <div> tag are a division and defines the space and needs a closing tag. Select the text that you want to scroll and apply the CSS style to the text you want in the scrollbox and you've got a scroll box. Note that the text will show up in the defined box but the scrollbar will not appear unless you preview it.
