Tizag: best site for student-friendly coding

I'm not a web designer by trade. I end up doing plenty of web design and coding, but it's certainly not my primary job. I have yet to find any good free, open source WYSIWYG editors, so I stick with Eclipse (and, more recently, with Aptana Studio, an Eclipse derivative). Our student information system allows announcements to include embedded HTML and Google Docs hasn't integrated CSS changes into their GUI yet, so I spend a decent amount of time looking at code. Just not enough to avoid forgetting it.

Enter Tizag.com, one of the best reference and introductory tutorial sites for HTML, Cascading Style Sheets, PHP, JavaScript, and SQL. Not only do I use it all the time, but we use it consistently with our students to supplement or replace books (depending upon the class). Perhaps the most useful piece is simply their HTML tag reference. For those of us who use HTML regularly but not daily, it's far easier to have a handy lookup for tags and attributes than it is to keep them all memorized.

Similarly, their CSS tutorial, reference, and examples are more than enough to take any student with a working knowledge of HTML and get them using CSS. Since these are really becoming the standard in web design, the reference is timely.

Interestingly, a student first showed me Tizag a few years ago when he used it to teach himself PHP. Their PHP reference is that good: he easily developed adequate skill to build a site in PHP and then ask the right questions as he built his knowledge beyond what was available on Tizag.
