What tool should you use to validate HTML5 assets before uploading?

• A. HTML5 Checker
• B. HTML5 Studio
• C. HTML5 Inspector
• D. HTML5 Validator

Answer: (D)

Validating HTML5 markup before uploading ensures your pages adhere to the HTML5 specification, catch syntax mistakes, unclosed tags, missing attributes, and accessibility issues, and prevent rendering problems in production. The HTML5 Validator is designed for this purpose: it checks your HTML5 documents against the official HTML5 rules and reports errors and warnings that you can fix. This direct verification of conformance makes it the best tool for ensuring clean, reliable HTML5 assets before they go live. The other names aren’t established validation tools. A term like HTML5 Checker, HTML5 Studio, or HTML5 Inspector might imply inspection or different functionality, but they aren’t recognized as standard HTML5 validators. For reliable results, use a validator that explicitly checks against HTML5 standards (for example, the W3C HTML Validator or equivalent integrated tools).
