Why Validate HTML

Browsers display pages by inferring missing markup even when there are minor syntax errors, so errors often remain invisible in the rendered output. Ignoring them can lead to layout breaks across different environments and misinterpretation by search engines and screen readers.

Difference Between Errors and Warnings

Errors indicate violations of HTML specifications, while warnings point to non-conforming but discouraged syntax. The standard approach is to first eliminate all errors, then review warnings individually and decide whether to fix each one.
