Creating HTML documents is actually quite easy—HTML documents are simply text files embedded with HTML commands. You can create the documents with any editor capable of exporting raw text. In addition, HTML browsers are very forgiving about white space—additional tabs, line feeds, or spaces don’t matter.
As you create your first few HTML files, it is important to start using some good coding habits, habits that will serve you well as you code more complex pages later on. For example, consider the practices outlined in the following sections.
Use liberal white space
Insert liberal line breaks to separate code sections, and use spaces to indent subsequent elements. Both of these will help you read and understand your code. Consider the following two code samples:
As you can tell, the second example is much easier to read and, hence, easier to troubleshoot.
Use well-formed HTML
Well-formed HTML means that your documents need to have the following characteristics:
Note how the bold and paragraph tags overlap at the end of the block. Instead, the bold tag should have been closed first, as in the following example:
Element and attribute names must be in lowercase. XHTML is case-sensitive; the tag <HR> is different from the tag <hr>. All the tags in the XHTML
Document Type Definitions (DTDs) are lowercase—so your documents’ tags need to be, as well.
Instead, each open paragraph tag needs to be closed.
The first tag is incorrect because the attribute value is not quoted. The second is correct because the attribute is correctly quoted.
The first tag has a minimized attribute; the checked attribute is named but has no value.
Comment your code
Well-written code should speak for itself. However, there are plenty of instances when including comments in your code is warranted. For example, you will learn how to use nested tables to create complex textual layouts. However, such constructs often result in code such as the following:
Without comments, the nested tables are hard to follow. However, adding a few comments allows you to more easily keep track of the nested elements’ purpose:
