One of my colleagues has just reminded me that I never mentioned where I learned to do all the (admittedly limited) CSS stuff I’ve been doing over the weekend. Same place I’ve learned most of what I know about HTML and XHTML standards – W3Schools. They do some very nice tutorials and reference material, and it’s all available online for free. Nice people.
Another handy resource worth mentioning is HTML-Tags, from Visibone. They’re the same people who made the web safe colour lab – not as vital as it once was, now that pretty much everyone can display millions of colours, but still a great starting point for choosing a colour scheme. They make a living by selling some very nice looking quick reference cards and posters.
