A web standards checklist

What are web standards?

The term 'web standards' can mean different things to different people. For some, it is building websites without tables, for others it is using valid code. However, web standards are much broader than this. Web standards could be defined as:

The adherence to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursuit of best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc).

In other words...

A site built to web standards should be lean, clean, CSS-based, accessible, usable and search engine friendly.
