# This document has heading elements but none of them has a computed heading level of 1. > Canonical HTML version: https://rocketvalidator.com/html-validation/this-document-has-heading-elements-but-none-of-them-has-a-computed-heading-level-of-1 > Attribution: Rocket Validator (https://rocketvalidator.com) > License: CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/) A document lacks a heading with a computed level of 1, which means there is no `

` element (or an element whose final heading level resolves to 1) on the page. The W3C validator raises this as a warning because every document should have at least one `

` to identify its main topic. Screen readers and search engines rely on the heading hierarchy to understand page structure, and `

` is the expected entry point of that hierarchy. A "computed heading level" differs from the literal tag name only when the now-obsolete `` algorithm or the abandoned outline algorithm would adjust levels. In practice, for nearly all documents, a computed level of 1 simply means an `
` tag. This warning appears when a page uses `
`, `
`, or other headings but skips `
` entirely. Adding a single `
` that describes the page content fixes the warning. ## Example with the warning ```html My page
