Use Block Quotes
If you’d like to visually call attention to a quoted passage, as above, you can use the “block quote” button on the Editing Toolbar.
Type or paste the text into the edit screen of the page. Highlight it, and then click the Quotation Mark button on the editing toolbar.
Note: in the editing screen, the formatting won’t appear. It will look like this:
However, if you “Preview” the page (or view the published page after saving it), you will see the shaded textbox with the large callout quotation mark formatting.
