Inserting ruling lines
You can insert a horizontal ruling line – aka divider, dividing line, or rule – into a site page, page template, or event description.
To insert a divider or ruling line, click within the content gadget or event description where you want the divider to appear then click the Divider icon within the content editor toolbar.
From the dialog that appears, select the line style you want to use, the line color, and the line weight, then click the Save button.
The divider should now appear within the gadget or event description.
The Insert divider option is not available when editing an email. You can, however, insert a simple ruling line in an email by adding an <HR> tag to the HTML.
