H1Page

H1Page is a term used in web development to denote the primary heading element of a web page. It is not an official HTML tag or feature, but a naming convention found in templates, documentation, and codebases to refer to the page's main title.

In template systems and content management workflows, h1Page often maps to the content inside the main h1 element or to a variable supplying the page title. It is used to connect the visible heading with underlying data, such as article.title or site.title, keeping the heading consistent across the page.

In practice, h1Page appears as a reference point for rendering, validation, and scripting. Templates may render h1Page directly, while scripts may locate the heading to read, replace, or annotate it for features like dynamic breadcrumbs or accessibility support.

From an accessibility and search engine perspective, the h1Page should be the highest level heading on the page and should convey the page’s purpose clearly. A unique and descriptive heading aids screen readers and helps search engines understand page structure.

Because h1Page is not standardized, developers may use different variants to name the same concept, such as mainHeading, pageTitle, or topHeading. The term is most common in internal documentation and starter templates rather than official specifications.
