Welcome Sara! I was in communications for 10 years before realizing how much I hated it. So I switched my career to web design. I am having A LOT of fun doing it.
My brother bought me a book called Head First
HTML. It's a little silly sometimes, but I think that's why I could follow it so well. Less technical mumbo jumbo to wade through. The pace is perfect and it keeps you interested. It's a giant tutorial you can do on your own time and it teaches you the basics for little cost. I think it's an excellent jumping off point to understanding how it all works. I will continue with my studies using the Head First series.
I use Dreamweaver to set up my designs and also to teach myself more about hand coding. I would set up a basic template in the editor then read the code above and experiment with it to get my desired results. At this point I start a completely blank template and hand write almost all of the code except for simple things that are just easier in DW.
DW has quirks I found... which is why it's truly best to learn how to write the code in case you need to tweak something. I can't rely on it for everything and
I learned
CSS accidentally by doing a tutorial for creating Wordpress templates. My goal wasn't to learn
CSS at that point, but it taught me a lot and I was able to take it from there on my own. I'm hoping Head First has a
CSS book so I can learn the rest of what I haven't figured out on my own yet. I may need a more advanced manual though. I'm not sure yet. I've learned other techniques just by searching on the net for tutorials.
I learn by doing. I'm lucky enough to have a part time job where I can take the time to learn... and get paid to do it. But I'm on my own. No one here can teach me and I can't afford classes.
I'm not sure if this is what you're looking for, but it's how I got started and am continuing to teach myself for very little cost. It takes self motivation to keep going through the books and trying new things.
Another book I recommend is the Web Design Index. I have version 7. It is nothing more than a book full of sample websites. When I see something I like, I try to duplicate the look. That is how I am learning.
