RULES FOR WRITING HTML5 CODES
There are certain rules for writing HTML codes. Lets us learn more about them:
• Container tags should always be closed properly.
• Values given to the attributes should be enclosed within the double quotes.
• Tag name should not contain spaces.
• There should be no spaces between < and > in a tag.
• Tags must be nested correctly.
HTML5 DOCUMENT STRUCTURE
An HTML document is a text file containing markup tags. The markup tags tell the Web browser how
to display the web page. A HTML file is saved with .htm or .html extension.
Basic Structure of HTML Document is as follows:
<!DOCTYPE html>
<html>
<head>
<title>Title of the web page</title>
</head>
<body>
Content of the page
</body>
</html>
A HTML page is divided into two sections called Head and Body.
• Head contains the information which is not to be shown on the web page.
• Body contains the information which is to be shown on the web page.
HTML provides various tags such as <!DOCTYPE html>, <HTML>, <HEAD>, <TITLE>, <BODY>, and
many more. Let us discuss some tags in detail.
The <!DOCTYPE HTML> Tag
The <!DOCTYPE html> is not an element in HTML. It is a document type declaration that tells the
browser about the version of HTML. It is not case-sensitive which means you can write it into
uppercase or lowercase.
The <HTML> Tag
The <HTML> tag tells the web browser that the text contained between <html> and </html> is a web
page and can be viewed using a web browser. Every web page coding must start with the <html> tag
and ends with the </html> tag.
