You can insert a box into a topic and add content to it. The text box is separate from the regular text in the topic and can be positioned in a variety of places on a page (e.g., aligned left on the page, outside frame, center of column). You might add a text box, for example, to create an example or case study that runs alongside the main text in a topic, in order to enhance the reader's understanding of the main text. See Inserting Text Boxes and Positioning Text Boxes.
example
Let's say you want to add a case study that is positioned next to the main body text on a page. Therefore, you insert a text box with a border and unique background color to make it stand out. You position the text box to the left of the body frame on a page. That way, it is clear to the reader that the case study is intended to provide additional information pertaining to the body text on that page.
When you insert a text box, you can make selections to affect the look of the box (e.g., border background, size).
Note: Text boxes are not supported in Microsoft Word output.
