Validating HTML
HTML validation tools can identify syntax and structural problems. Validation is useful, but valid markup alone does not guarantee accessibility, good UX, security, or correct application behavior. Testing should include keyboard navigation, screen readers where appropriate, responsive layouts, and real user workflows.
Validation Is Only One Layer
Treat HTML validation as one part of a broader quality process rather than as proof that a page is fully correct.
Key Takeaways
- Validate HTML during development.
- Combine validation with accessibility and functional testing.
