There are several custom button options for your site.  You can highlight text in your content area, select the link icon to assign a link and then choose the button class from the formats menu.  The class must be assigned to the link.  The options are .button-small, .button-medium, .button-large. If the section has a dark background, the color will adjust accordingly. The style guide page displays each of these.

You can add the following classes to achieve the corresponding colors to text:

• orange-text
• green-text
• blue-text
• red-text
• grey-text

If you would like to display an image inside a column at fullwidth of the column container you can add the class "responsive-image" to the image tag.
