Modal with CSS (web only)
If you choose to use a web-only Web Modal with CSS message, you can apply your own template or write your own CSS in the provided space. This space is already pre-filled with the CSS shown in your message preview, but feel free to adjust it slightly to meet your needs.
If you choose to apply your own template, click Apply Template and choose from the in-app message template gallery. If you don’t have any options, you can upload a CSS Template using the CSS Template builder.
