                     non-text items within it. Each tag in HTML follows specific rules and syntax. HTML tags are not case-sensitive.
     Hypertext is a piece of text that has the special feature of linking to another document or web page.  In HTML document, a tag name begins with an opening angular bracket (<) and  ends with closing

     Markup Language  angular bracket (>). For example,

     Some of the important features of HTML5 are:  a forward slash before the  tag name. Most of  the  tags in  HTML  have opening  and  closing  tags. A

       It allows us to build tables.  The HTML tags can be categorised as:
       It allows us to add links on the web page.    Container Tags: The tags that have both opening and closing tags are called Container Tags.

       It is not a case-sensitive language.     For example   <b> ...... </b>
       It is a very easy and simple language.                     <head> ...... </head>
        It provides a flexible way to design web pages along with the text.     Empty Tags: Empty tags contain only an opening tag. They do not have a closing tag. These tags do
                       not enclose any data.
     Types of HTML Editor     For example   <br>, <hr>, etc.

     There are mainly two types of HTML editors: WYSIWYG editors and Text editors. Let us now discuss   HTML tags can also be further classified as:
     these editors.      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.

     graphical interfaces for designing web pages. Examples of WYSIWYG editors are Adobe Dreamweaver,
     Amaya and Google Web Designer.  Nesting of tags means that you can start a new tag before closing the previous tag. The key point to
                     remember is that tags are nested based on the LIFO principle, that is, Last In First Out. This means that
