The W3C is the World Wide Web Consortium, and since 1994 the W3C has provided the guidelines by which websites and web pages should be structured and created. The rules they outline are based on the best practices and while websites don't have to comply to be viewed correctly in Internet Explorer and other popular browsers that cater to incorrect design practices, there are a number of compelling reasons to ensure that we ensure that the W3C guidelines are followed and that the site is brought into compliance.
Some reasons for W3C compliance are:
• To help ensure accessibility for the disabled.
• To help ensure that our website is accessible from a number of devices; from different browsers to the growing number of surfers using PDAs and cellular phones.
• To help ensure that regardless of the browser, resolution, device, etc. that our website will look and function in the same or at least a very similar fashion.
