Hypertext Markup Language (HTML), is a computer language that tells browsers how to display website content. The Custom HTML block allows you to insert this code and preview it as you edit to fine-tune your content.
📌
For security reasons, not all HTML tags are allowed in the Custom HTML block. Please check the list of supported HTML tags for the ones you can use.
