On subsequent visits to the page, the user recollects this visual model. A non-sighted user will typically want to do exactly the same, using their screen reader to scan for headings to create a mental model. ### Working Examples *The content for this section is not yet available, please check back again for updates.* ### Best Practices Every page **must** have a single H1 heading. The H1 heading **should** describe the content and purpose of the page. The H1 heading does *not* need to be the first heading in the page. Every page region requires a single H2 heading. This heading describes the content and purpose of the region. It is good practice to wrap every page region in a div or section tag. Every page region can contain multiple H3 - H6 headings, but they *must* be placed in the markup in strict hierarchical order. ### Interaction Design This section provides interaction design for keyboard, screen reader and pointing devices. #### Keyboard Headings are not interactive elements and therefore have no keyboard interaction. **NOTE**: headings can *contain* links, which *are* interactive elements. #### Screen Reader Screen reader will identify heading by it's level, e.g. 1 to 6. #### Pointer Headings are not interactive elements and therefore have no pointer interaction. A heading may give the illusion of being an interactive element if it contains a link, or is wrapped in a link, but the heading element itself is not clickable. ### Developer Guide *The content for this section is not yet available, please check back again for updates.* --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ebay.gitbook.io/mindpatterns/structure/heading.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
