Basic HTML Document

In its simplest form, following is an example of an HTML document:

<!DOCTYPE html>
  <html>
  

   <head>
      <title>Example of a document title</title>
   <head>
	

   <body>
      <h1>This is a heading</h1>
      <p>Document paragraph or sentence goes here…</p>
   <body>
  

	</html>

HTML Tags

As told earlier, HTML is a markup language and makes use of various tags to format the content. These tags are enclosed within angle braces <tag>. 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:

<!DOCTYPE...> - 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> and document body which is represented by <body> tags.
<head> - This tag represents the document's header which can keep other HTML tags like <title>, <link> etc.
<title> - The tag is used inside the <head> tag to mention the document title.
<body> - This tag represents the document's body which keeps other HTML tags like <h1>, <div>, <p>, and so much more.
<h1> - The <h1> represents the heading, unlike the other headings <h2>, <h3>, <h4>, etc.
<p> - This tag represents a paragraph.

To learn HTML, you will need to study various tags and understand how they behave, while formatting a textual document. Learning HTML is simple as users have to learn the usage of different tags in order to format the text or images to make a beautiful webpage.

W3C recommends to use lowercase tags starting from in HTML document.
