Westciv, the publishers of a number of comprehensive self paced courses for learning CSS, HTML/XHTML and standards based design are giving away a completely free (X)HTML and CSS online course. If you are serious about learning and knowing standards based web design this is a free lunch worth saying yes too. According to some of the blogs in my feedreader this course has been around for some time, but has now been updated to better reflect modern browser’s support. I haven’t done the course myself, but as I understand this course has been the foundation for many of today’s well known designers. Furthermore it’s said to be good for a learner to intermediate level.
If this is old news to you, and you think you know everything there is to know, then why don’t you join Molly in her quest for making the www a better place?
