The following site and page elements can be configured with custom HTML and CSS:
- Site header

A site's pages automatically use the site's header and footer.
Add HTML or CSS to headers and footers
Add custom code to the layout
To add code to the layout of you site or page, use the text card. Use the Code View option on the text card to format your layout with custom code anywhere that you can add a text card. You can also apply CSS to a row in the row's settings. For more information, see Customize text with HTML.
