Update 10/2018: CSS and HTML are now available on the Advanced and Power plans. If you are on the Basic or Standard plans, you will need to upgrade to use custom CSS or HTML.
Whether you want to customize one part of your campaign, or you want to fully customize the styles of multiple parts, it can be done with CSS in Woobox offers. We’ve compiled a list of some of the more common CSS reference requests (i.e., what item should be referenced in custom CSS in order to change the styling of the element), which we hope you’ll find helpful.
If you have found a part of your campaign that cannot be changed easily and you need help, feel free to email us at firstname.lastname@example.org
