There are three button colors that can be used in the CMS. They can easily be created when you set up your link or you can use the Buttons in a Row snippet to create multiple buttons in a row.
This snippet creates a row of buttons that link to other pages or websites. The default button style is the “blank” style. When hovering over the button it gets a gold fill. The button width changes to fit all buttons evenly in the available area and the height changes to fit all link text.
