10 rules of HTML document

Answer: There are five important rules for coding with HTML tags:--
1>Tags are always surrounded by angle brackets (less-than/greater-than characters), as in <HEAD>.
2>Most tags come in pairs and surround the material they affect. They work like a light switch: the first tag turns the action on, and the second turns it off. (There are some exceptions. For instance, the <BR> tag creates a blank line and doesn't have an "off switch." Once you've made a line break, you can't unmake it.)
3>The second tag—the "off switch"—always starts with a forward slash. For example, you turn on bold with <B>, shout your piece, and then go back to regular text with </B>.
4>First tag on, last tag off. Tags are embedded, so when you start a tag within another tag, you have to close that inner tag before closing the outer tag. For instance, the page will not display properly with the tags in this order:
<HEAD><TITLE>Your text</HEAD></TITLE>.
The correct order is:
<HEAD><TITLE>Your text</TITLE></HEAD>.
5>Many tags have optional attributes that use values to modify the tag's behavior. The <P> (paragraph) tag's ALIGN attribute, for instance, lets you change the default (left) paragraph alignment. For example, <P ALIGN=CENTER> centers the next paragraph on the page.
Remember, too, that HTML is always evolving, and older browsers often don't support the newest tags.
