Description: Validation errors are issues that arise when a web page does not conform to specified standards, which can affect performance. These errors can manifest in various ways, such as improperly closed HTML tags, incorrect attributes, or the use of deprecated elements. Validation is crucial to ensure that a web page’s code is interpreted correctly by web browsers, which in turn influences user experience and performance optimization. When a page has validation errors, it may experience rendering issues, slower load times, and unexpected behaviors. Additionally, search engines may penalize pages with errors, affecting their ranking in search results. Therefore, validation is not only a matter of compliance with standards but is also essential for accessibility and usability of a website. Implementing validation tools and periodically reviewing code are best practices to minimize these errors and ensure optimal web performance.
