Web Standards

HTML can be coded in numerous ways. And browsers can read HTML in just as many ways. You could say that HTML has many dialects. That is why some websites look different in different web browsers.

W3C is the World Wide Web Consortium, which is an independent organization that governs web code standards such as HTML, CSS, XML and others. Microsoft, The Mozilla Foundation and many others are a part of W3C and agree on the future developments of web standards.

If you are like me working on with web design, you probably know that can be a big differences in how a webpage is illustrated across different browsers. It can be very irritating and time consuming to start a webpage which can be viewed in Firefox, Internet Explorer, Opera and all the rest of the web browsers.

The concept of having web standards is to agree on a common portion on how to use web technologies. This implies that by certifying web standards, a web developer has a certainty that what he or she does will work in a more proper manner across different platforms. I therefore recommend that you back up the work carried out by the W3C and validate your HTML and CSS to web standard.

To validate your HTML markup go to W3C HTML validator.

CSS Validator

To make it easier to observe the CSS standard, W3C has made a CSS validator which reads your stylesheet and returns a status listing errors and warnings, if your CSS does not validate. Validate your code with the CSS Validator.
