HTML: structured document, Hypertext Markup Language

(1) Four Basic Rules

1. Each start mark must be used together with the end mark. // <Tag> </tag>

2. The document must contain unique Open and Close tags. All other tags in the document must be included in these two tags.

In eg. state XML, <state> </state> is the only flag to open. Other tags must be included in the two tags.

3. the tags in the document cannot overlap.

Eg. <name> <population> </name> </population> is invalid.

4. the attribute of an element must have an attribute value, which must be caused by single or double quotation marks.
