That's a really nice, straight-forward tute for getting started. I'd like to add my own two recommendations to it:
1) Forget about using Notepad. Or any other simple text editor intended for plain text. You will drive yourself batty & get eye strain staring at code in it. Instead, do yourself a favor and download Notepad++ which is a TOTALLY FREE editor that despite the name has nothing to do with Microsoft's Notepad.
With Notepad++ you can have two tabs open side by side which is unbelievably handy when you are copying & pasting code from one doc to another and is ideal for comparing two docs line by line, such as say a template you are using that you don't want to muck with, to a new page you're creating with that same code that you'll be editing. It has a ton of bells & whistles, more than the average Joe including self would ever need, but the #1 thing for me is how visually easy it makes editing code. You pick the language you want it displayed in (HTML or CSS for example) and each language has a default style applied to it to make it easy to read. But there's a very easy to use style configurer to set your own font style & colors and/or highlight colors for the different parts of a code in whatever way is easiest for you to read.
This screenshot shows the same piece of example code (copied from the Nifty bookmarklet tool) in two tabs. I have HTML set as the language and my own custom style applied. Below that is what the same piece of code looks like in Notepad. Ughh! Look how hard that would be to work with. Even if just dabbling starting out, having a decent editor meant for code and not just plain text will make the learning experience less frustrating.
2) You can quickly test snippets of code here: TryIt Editor
Delete the default sample content in the left pane, paste in your own code, and click the green Run button to see the results rendered in the right pane. Here's the sample code from the above screenshot in the TryIt editor:
It may seem really difficult & time consuming at first, but once you get the hang of the basics it's very satisfying to know you can control the look of your content without having to completely rely on code that was auto-generated for you somewhere.
