Why Web Standards?

Web standards make Web development easier.

To make internet a better place, for both developers and end-users, it is important that both browsers and Web developers follow the Web standards.

The term web standards can mean different things to different people. For some, it is ‘table-free sites‘, for others it is ‘using valid code‘. However, web standards are much broader than that. A site built to web standards should adhere to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursue best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc).

In other words, a site built to web standards should ideally be lean, clean, CSS-based, accessible, usable and search engine friendly.

About the checklist

This is not an uber-checklist. There are probably many items that could be added. More importantly, it should not be seen as a list of items that must be addressed on every site that you develop. It is simply a guide that can be used:

Tip: Make a habit of validating your pages with a validation service. Validation keeps your documents up to the standards, and free for errors.
