Semantic HTML Advisor

v1.1.0

Review HTML structure for semantic correctness and accessibility.

Analyses HTML markup for semantic correctness — flags overuse of generic div/span elements, missing ARIA roles, inappropriate heading nesting, and suggests semantic replacements (section, article, aside, nav, main, header, footer).

How to use
  • →Paste your HTML into the input area and click Analyse to see the semantic findings.
  • →Red items indicate semantically incorrect usage (e.g. a div used as a button without role="button").
  • →Click any finding to see the suggested semantic replacement and a code example.
  • →Export the report to track semantic HTML improvements across your codebase or design system.
