1 What are HTML validators?

HTML validators are online or offline tools that check your HTML code for errors, warnings, and compliance with the specifications and best practices of the World Wide Web Consortium (W3C), the organization that develops and maintains the HTML standards. HTML validators can also provide feedback on the structure, semantics, and accessibility of your web pages.

2 How do HTML validators work?

HTML validators work by parsing your HTML code and comparing it with the rules and guidelines of the chosen HTML version or doctype. They can identify and highlight any syntax errors, such as missing tags, attributes, or quotes, or any deprecated or non-standard elements or attributes. They can also warn you about potential issues, such as missing alt attributes for images, or suggest improvements, such as adding headings or labels for forms.

3 How can HTML validators benefit you?

As a web developer, HTML validators can offer several advantages. They can help you learn and improve your HTML skills by demonstrating mistakes and how to fix them. Furthermore, validators can ensure your code is valid, clean, and consistent, which can boost web page performance, SEO, and cross-browser compatibility. Additionally, validators can enhance the usability, accessibility, and user experience of your web pages by following the web standards and best practices. Last but not least, HTML validators can save you time and frustration by debugging and testing your code before publishing it online.

4 How to use HTML validators?

Depending on your needs and preferences, there are various types of HTML validators you can use. Online validators, such as W3C Markup Validation Service, HTML5 Validator, and Nu Html Checker, enable you to validate your code by entering a URL, uploading a file, or pasting the code directly into a text box. Browser extensions, like HTML Validator for Firefox, Web Developer for Chrome, and HTML Tidy for Safari, allow you to validate your HTML code by clicking a button or using a keyboard shortcut. Code editors, like Visual Studio Code, Sublime Text, and Atom also have built-in or integrated validation features that can be used to write and edit your HTML code.

5 How to interpret HTML validator results?

When you use an HTML validator, you will get a report that indicates whether your code is valid or not and how many errors and warnings were found. This report will also list the errors and warnings, with the line and column number, the type and description of the problem, and sometimes a suggestion or explanation on how to fix it. Additionally, it will provide a source view with your HTML code marked with errors and warnings, as well as a preview or outline view of your web page. To interpret these results, you should pay attention to the errors and warnings and try to understand their meaning and effect on your web page. It is important to fix them as soon as possible, starting with the most severe ones. You can use the validator's feedback, documentation, or online resources to help you resolve the issues and improve your code quality.
