What is used to validate HTML and CSS code?

Explanation:
Validating HTML and CSS means checking that the code follows the official specifications so browsers render it consistently and assistive technologies can interpret it correctly. The W3C Validator is the standard tool for this purpose; it validates HTML, XHTML, and CSS against the W3C specifications, catching syntax errors like unclosed or mismatched tags, incorrect nesting, missing Doctype declarations, and invalid CSS properties or values. This kind of validation helps prevent rendering quirks across browsers and improves accessibility. Tools like JSLint and ESLint are JavaScript linters and don’t validate HTML or CSS, and HTML Validator Pro isn’t the recognized standard validator for HTML/CSS.
