In HTML document, a tag name begins with an opening angular bracket (<) and  ends with closing
                  angular bracket (>). For example,
                                            <TagName> content </TagName>





                                              Opening tag                   Closing tag

                  Both  opening and  closing  tags  are  the  same.  The only  difference  is  that  the  closing  tag  contains

                  a  forward slash before  the  tag  name.  Most  of the  tags  in  HTML have opening  and  closing  tags.
                  A combination of opening tag, content, and closing tag is called an element.
                  The HTML tags can be categorised as:

                     Container Tags: The tags that have both opening and closing tags are called Container Tags.
                    For example:       <B> ...... </B>

                                             <HEAD> ...... </HEAD>
                      Empty Tags: Empty tags contain only opening tag. They do not have a closing tag. These tags do not
                    enclose any data.
                    For example:       <BR>, <HR>, etc.

                  HTML tags can also be further classified as:
                      Block Level Tags: The block level tags take up the full width available and by default begin on a

                    new line. Some of the block level tags are Paragraph <P>, headings <H1> to <H6>, Horizontal Rule
                    <HR>, etc.
                      Text Level Tags: The text level tags are used to mark up parts of the text. These tags do not start
                    with a new line. Some of the text level tags are Bold <B>, Superscript <SUP>, Italic <I>, Subscript

                    <SUB>, etc.

                       Nesting of Tags

                  Nesting of tags means that you can start a new tag before closing the previous tag. The only point to
                  remember is that tags are nested on LIFO principle, that is, Last In First Out. This means that the tag
                  that has been opened last needs to be closed first.

                       Attribute

                  An attribute is a property that provides some additional information about a tag. It enhances the

                  functionality of a tag. It is always specified inside the opening tag. All attributes consist of two parts:
                  a name and a value.
                  The ‘name’ is the property that you want to set.

                  The ‘value’ is what you want for that respective property.
