Beginning HTML - Comments
(Page 4 of 5 )
You will notice in the above coding sample a line that says <! I am a comment! The computer does not see me tee-hee!>. This is known as a comment line. When the browser sees the <! > it turns a blind eye to whatever is in the comment tag and does not read it.
Comments are used to remind yourself and to tell other programmers the purpose of specific pieces of code. That way when you look at your code a year later or the person who replaces you looks at it, they understand more easily what you were trying to accomplish should a problem arise or a modification be needed. They aren't necessary, but it is considered good programming practice to include them.
Horizontal Rules!
If this weren't a pg-13 audience I might take the time to explain that. Horizontal rules are a good way to separate lists of data or sections of documents. Basically, it inserts a line like the one below:
To insert a horizontal rule, just use the <hr> tag.
Aligning
To align text, observe the following code:
<html>
<body>
<h1 align="center">This is heading 1</h1>
<p align="right">This paragraph is right aligned </p>
<p>This paragraph is left aligned by default </p>
<p align="center">This paragraph is centered</p>
</body>
</html>
This gives us the following output:
This is heading 1
This paragraph is right aligned
This paragraph is left aligned by default
This paragraph is centered
Changing the Color of Your Background
Changing the color of your background is pretty simple also. Look at this code:
<html>
<body bgcolor="purple">
<h1>Example of a colored background</h1>
</body>
</html>
This will change your background to purple. If you want it red, replace the word purple with red, etc. We will go over the available colors and color codes later on in this tutorial.
