Setting up a top caption is very easy because all it really is, is a text widget.
- Go to your Widget Manager
- Drag a text widget into the Top Caption widget position
- Enter in your caption text or whatever content you wish to put in
- Click Save and view it on the front-end
Suggestion: Try to focus on search engine optimization (seo) by putting keywords related to the page you will display it on (or pages). If you use the “Widget Logic” plugin, you can manage where your caption widgets will go.
