Element content
The HTML element content is everything that goes between start and end tags. If it's a heading — <h1>Hello, World!</h1> — the text "Hello, World!" is the content, and users will see it as the main headline on a page. However, some parts of the element content can stay invisible to viewers. For example, if it's a <title> element, it appears only on a browser tab bar and in search results.
