HTML validation and testing

HTML validation and testing are important steps in the web development process. HTML validation checks the syntax and structure of your HTML code, while testing ensures that your web pages function correctly and are compatible with different devices and browsers.

  • HTML Validation

HTML validation is the process of checking your HTML code for errors and ensuring that it follows the proper syntax and structure. Validation can be done using online tools such as the W3C Markup Validation Service, which checks your code against HTML standards and provides feedback on any errors or warnings.

  • Testing

Testing ensures that your web pages function correctly and are compatible with different devices and browsers. This includes testing for functionality, performance, and user experience. Here are some types of testing you should consider:

  • Cross-browser testing: Test your website on different browsers such as Chrome, Firefox, Safari, and Internet Explorer, to ensure that it works consistently across all of them.

  • Device testing: Test your website on different devices, such as smartphones, tablets, and desktop computers, to ensure that it functions correctly and is optimized for different screen sizes.

  • Accessibility testing: Test your website for accessibility to ensure that it is usable by people with disabilities. This includes testing for keyboard navigation, screen reader compatibility, and color contrast.

  • Performance testing: Test your website’s performance to ensure that it loads quickly and efficiently. This includes testing for page load time, page size, and server response time.
