Yes, it's possible. Is the font-awesome stylesheet AND fonts uploaded to Marketo? If so, make sure you update the font paths in the first couple lines in the stylesheet to reference the Marketo-hosted font files. font-family: 'FontAwesome'; src: url('../fonts/fontawesome-webfont.eot?v=4.6.3'); src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.6.3') format('embedded-opentype'), url('../fonts/fontawesome-webfont.woff2?v=4.6.3') format('woff2'), url('../fonts/fontawesome-webfont.woff?v=4.6.3') format('woff'), url('../fonts/fontawesome-webfont.ttf?v=4.6.3') format('truetype'), url('../fonts/fontawesome-webfont.svg?v=4.6.3#fontawesomeregular') format('svg'); font-weight: normal; font-style: normal; If you're using the font-awesome CDN or if the font-awesome stylesheet is not hosted in Marketo, the font might not display in the editor or the preview mode. It will only display when you approve the landing page and view the live version.
