Learn Simple Things First ¶
For the most parts (and especially if you start learning), it holds, that HTML 4 is a subset of HTML 5 and likewise CSS 2 of 3. Therefore my suggestion is to start learning the ‘old’ techniques first. This is especially motivated by the fact that the HTML5 and CSS3 specifications are way larger than their older counterparts. (In the News: This just in: "HTML" is the new "HTML5".)
There is another problem with HTML5 tutorials:
They pop up like daisies on a soft spring morning, which is per se a
good thing. But as rookie you will have difficulties to decide if a
given document aims at beginners or, more likely indeed, at
people with experiences in (X)HTML, who want to learn the
differences. It is easier to get confused by such an HTML5 intro, than by an
HTML4 tutorial (there was not really a big difference between HTML 3 and 4,
apart from paradigms [table-based layout,
font tag, stuff like
that was discussed then]).
‘My Way’ ¶
Everyone is different in her/his learning behaviour, so let me summarize the way I came to web development.
I didn’t have anything in mind with web development until I was a Physics undergrad student. Then I thought: ‘Well, it would be nice to have a customized start page for my browser.’ It was 2004, and iGoogle wasn’t invented back then. That’s it. You have a small project and you start to work on it.
I had the luck, that in the German speaking world there is a great resource for getting started with HTML: SelfHTML. Unfortunately, the site hasn’t had much updates since back then and their English counterpart went even out of business. Please don’t use the aforementioned W3Schools. However, I can’t point you to any good English tutorial apart from the specifications (see below). You might have luck finding a good course in the School of Webcraft, which is a joint venture of Mozilla and P2PU.
After finishing my browser start page, I created a homepage for our RPG group. It was several HTML pages and I quickly found out about CSS, and that you can have a single stylesheet to apply to more than one HTML pages. This is where I first started to think about the structure of the many files that had accumulated (in terms of ‘in which folder comes which file’).
Apart from that, you will find, that you have to learn a lot more accompanying technologies:
- I wanted a private area for our group and learned about HTTP Authentication.
- Having files lying in sub-directories brings you very fast to the matter of URLs and relative and absolute paths.
The next logical step is to move from static HTML files to something generated on the server. I took a very good beginner’s course in PHP and MySQL (it’s IMHO the simplest server-side technology to get started with) and got a bit of PHP-enabled web space at our university. A good ‘Hello World’ project was a guest book for the RPG website back then (well, today you’d just throw in a Disqus link).
Now I came to the frontiers of tutorials and references. I first really looked in and began to read the original specifications. It started with the official PHP manual and went on to the HTML 4 specification, single definitions of CSS properties in the W3C’s CSS 2 spec and so on. In hindsight this is another point I’d like to emphasize: read the specs as soon as possible. There will be parts that you don’t understand yet, but there is no better source than the source.
From there on it was a constant learning with many new technologies that require at least a bit of attention, but sometimes also a fundamental understanding: the DOM, CGI, SVG, XML, the difference between XHTML and HTML, Regular Expressions, Python, mod_rewrite, nginx, XSLT, PDF, RSS, RDF, Bash, SSH, Git, SVN, XSS, Unicode, Web Fonts, Dublin Core, JSON, SQLite, … (all links go to Wikipedia).
Finally you will come to a stage, where you need to specialize. The range goes roughly from "I’m a designer. I don’t touch no nasty code ever." to "B2B JSON is the best thing since JBoss and Hibernate. Good, that I don’t need Photoshop for this." I’m still trying to follow the naive approach to keep up to date in as many areas as possible, but I can foresee, that this strategy won’t be successful for long. In less than 5 years from now (and even today) you will find job descriptions for ‘
canvasdevelopers,’ ‘multimedia markup strategists,’ ‘cross-platform user experience experts,’ ‘specialists for legacy Flash code and table-based HTML Email templates,’ ‘offline cache security gurus,’ ‘web storage database engineers’ and so on. However, having at least a basic understanding in areas around your main interest will help to keep you flexible enough for new ideas and approaches (and, more important, old and tested ideas and approaches to problems you think are new).
Please, I don’t want to discourage you, when I say, that there’s a lot more to learn than HTML and CSS. I see it more as a wonderland of opportunities and technologies that lie at my finger tips to be used to create cool stuff. And the more you learn, the more powerful your projects will be.
In-Depth Learning ¶
When you have found a direction, that interests you most, you should start learning the backgrounds of your chosen path. This might seem a bit contradicting to what I said above about keeping a broad overview, but it is more a completion.
For example, if you tend to be a back-end developer, start looking into different algorithms, parser theory, cryptography, profiling code, building compilers and so on. The topics you encounter there might have no direct relation to your day-to-day problems, but they build the foundation of what you use today. As such, many problems were solved before, that re-occur today in slightly different form.
If you become a markup
specialist, look into text-manipulation tools. The Unix tools like
grep have got a bad name
as being old, arcane cruft, but this is totally unjustified. They, too, solve
problems, that you will face in your work.
For becoming a web designer you have to get into color theory, typography (both macro and micro), grid theory (which existed way before the web) and, at least, basic psychology.
Pay Attention ¶
The problem is learning from the wrong resources. I’d suggest, if you are in doubt, ask here on StackOverflow for opinions (better perhaps, ask over at chat.stackoverflow.com. And basically, the closer to the source a doc is, the better.
A personal warning: Leave your hands from WYSIWYG editors and such, like Dreamweaver. You may use an IDE or any editor with additional support (Eclipse comes to mind), but my travel went the other way round (from GoLive to Notepad++ to finally Vim). That’s a matter of taste. But if you have the slightest thought, that the software hides something from you or auto-creates anything that you haven’t told it explicitly to, leave it alone.
A basic measurement is, if your software let’s you choose the encoding of the file (ISO-8859-1, UTF-8, ...) and if or not to put a BOM in front of an UTF-8 file.

- XAMPP - A simple way to create an ApacheI remember, that one of the things that costed most of my time when setting up a web server for the first time, was figuring out, which web address to enter at the location bar. Usually, it’s
localhost. (web server), MySQL and PHP environment on Windows or Mac OSX
- Microformats.org - This is a bit advanced: Microformats try to express machine- and human-readable data at once in HTML. It sounds scarier than it really is, and from looking at how they try to accomplish things, you can learn much of how HTML elements and attributes should be used.
- CSS Resetr - CSS resets are quite en vogue since ~2007. These are small CSS stylesheets, that revert most of the default styles browsers give to elements (like the large, bold text and the margin of
h1elements). CSS Resetr let’s you play with different reset stylesheets of certain fame. I list it here, because it may give you a nice insight in what CSS rule affects which elements.
- FontSquirrel @font-face generator - That’s a nice way to play with the
@font-faceproperty of CSS 2.1. Look at the source, that gets generated for inspiration. Apart from that, you can use the Google WebFonts Directory for production.

StackOverflow Questions / Answers ¶
Actually, I’ve never used a book to learn HTML or CSS. But then, HTML 4 and CSS 2 are much more light-weighted than their newer counterparts. Quite blindly I can suggest books published by O’Reilly. The dozen or so (bash, Python, XSLT, …) I have from them are all well-written and technologically correct.

Final Note ¶
I am constantly learning new things and improving and deepening my knowledge of already learned technologies. If you start with HTML and CSS, and if you want to do it seriously, you will find many problems on your road. You’ll see code, where you have no clue, what it does, or how it even is valid. After some time you will have your first experience with security and its holes (and I’ll wish you these to be soft and not related to credit card details 😉 ).
But if you keep your eyes open, utilize often and early the "view Source" menu item, and ask questions (here, as a comment below an interesting blog post, ‘ask Google’), you will be a the top of people, who build the way the world is experiencing its information. And, over all, it’s fun!
