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 using LIFO principle.
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. An 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>
An HTML page is divided into two sections called Head and Body.
Head contains the information about the document, such as the title of the page, links to
stylesheets, and other data that is not directly visible to the user on the web page.
Body contains the information which is 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 in
uppercase or lowercase.
