You can add custom scripts, CSS, or other HTML to landing pages.
Marketo Support is not set up to assist with troubleshooting custom HTML. For HTML assistance, please consult a web developer.
1. Select your landing page and click Edit Draft.
2. In the landing page editor, drag in the HTML element.
3. Enter your custom HTML code and click Save.
Nice! Put any scripts or CSS you want in there.
Whenever possible, test your custom HTML source in a local environment before deploying it in a landing page.
