What is W3C compliance?
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 there are a number of compelling reasons to ensure that you or your designer ensure that the W3C guidelines are followed and that your site is brought into compliance.
- Compliance help ensure accessibility for the disabled.
- Compliance helps ensure that your website is accessible from a number of devices; from different browsers to the growing number of surfers using PDAs and mobile phones.
- Compliance will also help ensure that regardless of the browser, resolution, device, etc. that your website will look and function in the same or at least a very similar fashion.
Additionally compliance will, by necessity, make your site easily spidered and additionally allow you greater control over which portions of your content are given more weight by the search engines.
XHTML
Short for eXtensible HyperText Markup Language, a hybrid between HTML and XML specifically designed for net device displays. XHTML is significantly better than HTML, as it encourages good practice. If your site is compliant then it will have a positive impact on the sites accessibility, consistency, search engine performance etc etc.
CSS
Short for Cascading Style Sheets, CSS gives both web site developers and users more control over how pages are displayed. With CSS, designers can create style sheets that define how different elements, such as headers and links, appear. These style sheets can then be applied to any web page.
WAI
Short for the Web Accessibility Initiative, an initiative of the World Wide Web Consortium launched in 1997 to ensure that as the Internet grows in usage Web sites are designed to accommodate people with disabilities. This is becoming more relevant as internet usage increases.
