CHAPTER 3 ■ CREATING YOUR FIRST MAP • Quality Naturally, you want to look professional, and you just don’t look good with HTML that doesn’t validate. Invalid code is the sign of a developer who doesn’t know what he’s doing. What Flavor of HTML to Use Several flavors of HTML are in use today. The most common ones are HTML 4.01 and XHTML 1.0, but there are others such as XHTML 1.1 and HTML 5. I tend to use XHTML 1.0 Strict in my work. I like that it’s more structured than regular HTML, so all the examples throughout this book will be in this version. You could, of course, use HTML 4.01, but if you do, I recommend that you use the strict version of it. Right now there’s a lot of buzz around HTML 5. It looks really promising but is still in a draft version, and there will be some time before you can actually start using it in live applications. For test purposes or for personal projects, on the other hand, it’s entirely possible to start using it right away. In modern browsers such as Firefox 3.5 and Safari 4, there’s already some support for it, and they degrade gracefully for elements not yet supported. Check out these articles for more information on how to start using HTML 5 right now: • http://articles.sitepoint.com/article/html-5-snapshot-2009 • www.alistapart.com/articles/previewofhtml5 Validate Your Code So, how do you know that your HTML is correct? The best way is to check your code with W3C’s HTML validator. It validates all flavors of HTML. You validate your file by entering the URL to the web page you want validated. If your HTML file is on your computer or on a closed server, you can either upload the file or paste the code into a text field. If your code validates, you will get a nice green notification that the document has been successfully checked (Figure 3-1). 24
CHAPTER 3 ■ CREATING YOUR FIRST MAP Figure 3-1. A successfully checked web page, incidentally being the home page of my blog If, on the other hand, the page doesn’t validate, you will get an angry red message that tells you so (Figure 3-2). Don’t be intimidated by the number of errors. Often several errors depend on a single error, so it probably looks worse than it is. The good news is that you will get pointers to where the problems are, so it’s easy to find and correct them. 25
