This is good news for all of us in the ongoing pursuit to ensure our code validates.
The new Mark-Up validator allows me to validate an URL or a file-upload, plus has a ‘direct-input’ field where text can be copied-and-pasted too. These are certainly going to beneficial. Yes, the former two options are included with Chris Predericks extension – but there are locations where it is not available – therefore the w3.org validator is surely the easiest option to use!
For those who wish to check that all their linkage is working, the W3 now have a Link Checker.
This is a great service that allows you to ensure that all URL’s are correctly encoded plus link to actual websites. I can recall a time when this was a serious problem to one of my early attempts at web design!
The number one validation service at W3C is the CSS Validator.
This service has no-doubt proved invaluable to many web-designers around the world.
Amazingly, they also provide a service that combines a Server Log analysis engine with batch validation, link checking and other quality-oriented processing, for step-by-step improvement and maintenance of Web Site Quality.
