You can setup buttons by using the following code wrapped in square brackets —  — instead of parenthesis. WordPress will automatically apply the styles on the front end of the site.
- url — the URL you would like to button to point to
- text — the text you would like the button to have
Example Code: (Replacing parenthesis with square brackets)
(button url=”enter-the-url-here” text=”enter-the-button-text-here”)
