An HTML validator is a software application that checks the syntax of HTML code to ensure that it is well-formed and meets the standards set by the World Wide Web Consortium (W3C). A validator can be used to check the syntax of an entire website, or just a single web page.
When checking the syntax of HTML code, a validator will look for errors such as missing closing tags, incorrect nesting of tags, and invalid attribute values. If any errors are found, the validator will generate a list of them so that they can be fixed.
The W3C provides a free online HTML validator at https://validator.w3.org/.
How do I validate my HTML?
There are a few ways to validate HTML. One way is to use an online validator, such as the W3C Markup Validation Service (http://validator.w3.org/). This service will check your HTML code for any errors and give you a report of any problems it finds.
Another way to validate HTML is to use a local validator, such as the Nu Html Checker (http://validator.w3.org/nu/). This tool will also check your code for any errors and give you a report of any problems it finds.
Finally, you can also validate your HTML code by hand. This involves checking the code against a published specification, such as the W3C HTML specification (http://www.w3.org/TR/html5/). This can be a bit more difficult, but it can be a good way to learn more about HTML and how it should be structured.
What is the best HTML Validator?
There is no definitive answer to this question as there are a variety of HTML validators available, each with its own advantages and disadvantages. Some of the more popular HTML validators include the W3C Markup Validation Service, the HTML Tidy tool, and the Total Validator tool.
What is W3C HTML Validator? The W3C HTML Validator is a free software application that checks the syntax of HTML documents against the World Wide Web Consortium (W3C) standard.

How do I validate my website?
There are a few different ways that you can validate your website. One way is to use an online validator, such as the W3C Markup Validation Service (http://validator.w3.org/). This service will check your website's code for any errors or issues.
Another way to validate your website is to use a web browser extension or plugin. For example, the Firefox Web Developer plugin (https://addons.mozilla.org/en-US/firefox/addon/web-developer/) has a "Validate HTML" tool that will check your code for errors.
Finally, you can also validate your website's code manually. This involves checking the code yourself, or using a text editor with built-in validation features. For example, the Atom text editor (https://atom.io/) has a "linter-htmlhint" package that will lint your HTML code for errors.
