Deprecated HTML tags checker
Deprecated HTML tags checker identifies obsolete elements in fetched page markup. Review legacy code and plan supported replacements without changing content.
What is Deprecated HTML tags checker?
Deprecated HTML tags checker looks for obsolete HTML elements in a webpage response. It is useful when reviewing an older theme, inherited content, or a template that has accumulated legacy markup. The result identifies places to investigate rather than rewriting the document for you.
How to use this tool
Submit the page URL and review the total number of detected obsolete elements. Read the list of tag names and their counts, then inspect the corresponding content or template through your normal editing workflow. Check other pages that use the same template to understand the likely scope.
Understanding the results
The checker compares parsed elements with its built-in list of deprecated tags. It does not validate the entire document, inspect every attribute, or predict how each browser will render the page. An older tag can still display content, but a supported replacement may make the intended structure easier to maintain. Plan any replacement carefully and confirm that styling, reading order, and functionality remain appropriate.
Frequently asked questions
Will this automatically replace old markup?
No. The checker only reports findings. Use supported editor controls, theme updates, or vendor guidance when changing the source that produces the affected elements.
Does a clean result mean all HTML is valid?
No. It means no listed obsolete tags were found in the fetched response. Invalid nesting, missing attributes, and other document issues require their own review.
