Inserting a Rule in HTML

You can insert a horizontal line into the email (at the current position of the cursor) to help divide two sections:

  1. Click Insert ▸ Rule… in the menubar.

  2. Select width, size, and alignment.

  3. Select Shaded if wanted.

  4. Click Close.

Alternately, you can also use the icon in the second bar below the Subject line.
