             <title>This is document title</title>
       </head>
       <body>
                <h1>This is a heading</h1>
                <p>Document content goes here.....</p>
       </body>
</html>

HTML TAGS

 

As told earlier, HTML is a markup language and makes us
of various tags to format the content. These tags are
enclosed within angle braces <Tag Name>. Except few tags,
most of the tags have their corresponding closing tags. For
example, <html> has its closing tag</html> and <body> tag
has its closing tag </body> tag etc. 

 
Above example of HTML document uses the following tags: 

  

Tag

This tag defines the document type and HTML version.
<html>
This tag encloses the complete HTML document and mainly comprises of document header which is represented by <head>...</head> and document body which is represented by <body>...</body> tags.
<head>
This tag represents the document's header which can keep other HTML tags like <title>, <link> etc.
