Meet and Pass The W3C HTML and CSS Website Markup Validation Standards. Fix Those Website Errors Today 

The World Wide Web Consortium (W3C) developed specifications and guidelines to lead the Web to its full potential by creating universal standards for a website. Passing W3C validation is important, but can be extremely difficult to achieve. It is highly unlikely that your site will pass on the first try. That is where our 911WEBSITEREPAIR.com W3C Site Validation service can help. Our service includes both a "before and after" validation error report.

With W3C Markup Validation, your website will have faster page loading times and functionality that works consistently between browsers and operating systems.

911WEBSITEREPAIR.com provides a report indicating that the websites coding is correct or not. Errors are noted in a list. One error, such as neglecting to close a tag, can cause a cascade of errors through the page, producing dozens or even hundreds of noted errors. These errors often create extremely large error logs on your server. However when 911WEBSITEREPAIR.com addresses the first error listed, it may eliminate the "cascade errors”. By correcting these coding errors, your website will have faster page loading times and functionality that works consistently between browsers and operating systems.

What is Markup Validation? 

Most pages on the World Wide Web are written in computer languages (such as HTML) that allow Web authors to structure text, add multimedia content, and specify what appearance, or style, the result should have.

As for every language, these have their own grammar, vocabulary and syntax, and every document written with these computer languages are supposed to follow these rules. However, Just as texts in a natural language can include spelling or grammar errors, documents using Markup languages may (for various reasons) not be following these rules. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation. A document that passes this process with success is called valid. 

With these concepts in mind, we can define "markup validation" as the process of checking a Web document against the grammar it claims to be using.

 

Is validation some kind of quality control? 

Validity is one of the quality criteria for a Web page, but there are many others. In other words, a valid Web page is not necessarily a good web page, but an invalid Web page has little chance of being a good web page.

  

Does "valid" mean "quality approved by W3C"? 

For that reason, the fact that the W3C Markup Validator says that one page passes validation does not mean that W3C assesses that it is a good page. It only means that a tool (not necessarily without flaws) has found the page to comply with a specific set of rules. No more, no less.
 

 Is validity the same thing as conformance?

No, they are different concepts.

Markup languages are defined in technical specifications, which generally include a formal grammar. A document is valid when it is correctly written in accordance to the formal grammar, whereas conformance relates to the specification itself. The two might be equivalent, but in most cases, some conformance requirements can not be expressed in the grammar, making validity only a part of the conformance.

The Validator is sort of like lint for C. It compares your HTML document to the defined syntax of HTML and reports any discrepancies.
 

 

Why should I validate my HTML pages?

One of the important maxims of computer programming is: "Be conservative in what you produce; be liberal in what you accept." 

Browsers follow the second half of this maxim by accepting Web pages and trying to display them even if they're not legal HTML. Usually this means that the browser will try to make educated guesses about what you probably meant. The problem is that different browsers (or even different versions of the same browser) will make different guesses about the same illegal construct; worse, if your HTML is really pathological, the browser could get hopelessly confused and produce a mangled mess, or even crash. 

That's why you want to follow the first half of the maxim by making sure your pages are legal HTML.
