HTML Tags

What are HTML Tags?

Consider this example
<html>
<head>
<title>Your page title</title>
</head>
<body>
<!-- An HTML comment which is not displayed on the web page -->
<h1>Your page heading</h1>
<p>Your page content in a paragraph.</p>
</body>
</html>
The words <html>, <head>, <title>, </title>, </head>, <body>, <h1>, <p>, </p>, </h1>, </body>, </html> etc., are called HTML Tags.
The words <html>, <head>, <title>, <body>, <h1>, <p> etc., are called opening tags / start tags.
The words </html>, </head>, </title>, </body>, </h1>, </p> (with a back slash /) etc., are called closing tags / end tags.

What is the syntax to write an HTML Tag?

HTML Tags are not case sensitive and you are free to use both uppercase or lowercase tags or a combination of both. Now a days many websites use lowercase tags and for future specifications (versions) of HTML it is recommended to use lowercase tags.
Any number of line breaks and spaces in a HTML document are treated as a single space character (exception: <pre></pre> tag).

<p>Your page content in a paragraph.</p>
<p>
Your page    content         in a paragraph.
</p>
<p>
Your page
content in a paragraph.
</p>
<p>
Your page
   content in a       paragraph.
</p>
<p>
Your page
   content
   in        a paragraph.
</p>
The ouput of all the above codes is same.
