I'd recommend you lay off dreamweaver if you really want to learn the code. Unless you intend to work in Code view all the time. But actually using the tools provided by dreamweaver may make your code inefficient some times and you will not learn as much from it.
The way I learned it was by making a simple photoshop design, told a friend exactly what I wanted it to look like, he coded it for me, and then I looked at the code and examined how he accomplished what I wanted to do. I still look back on that very same code nowadays. It really helps if you have someone that can code very well
