Ok first a quick definition of what HTML is!
In layman's terms, HTML is a language recognised by the Internet, therefore if you know how to use it, you can play around with the Internet, the most popular use of HTML is for editing websites.
In this tutorial I will cover some of the basic HTML commands for use with notepad, which will be your program of choice when coding HTML, if you cant find it - It is in the accessories folder in program files.
Now to learn some basic tags
<html> This starts a html document
<head> This is the tag for the head area of the webpage, the part where the title and stuff goes.
<Title> This is where the title goes
<body> This is where you put the main content/body of the document.
So for example:
<html> Starts the html code
<head> Starts the head area
<title> Hello this is my first html document </title> Starts then ends the title area
</head> Ends title area
<body> Starts body area
<b> hello world </b> starts then ends Bold text command
</body> Ends the body area
</html>
Ends the html code
The document should look like this in notepad
