Example of an (very) simple web page:

<!DOCTYPE html>
<html>
<head>
<title>
A Simple Page</title>
</head>
<body>

Sample Text Sample Text Sample Text Sample Text Sample Text Sample Text<P>

<a href="url">link text</a>

</body>
</html>

What the Tags mean:

The <html> element is the root element of an HTML page. Any web page starts with <html> and ends with </html>. All the rest of the code is inserted between these two tags.

<!DOCTYPE html>
means HTML5

Directly following is the <head> and </head> tags. The <head> element contains meta information about the document. Inserted within these two are the <title> and </title> tags, where you specify in between a name
for the Web Page you are creating which will appear in the title bar of the browser window.

The rest of the texts and tags of the page are inserted between the <body> and </body> tags which so-can-say contain the BODY of the web page.

Other single tags include:
-the <br> tag which inserts a line break;
-the <p> tag which inserts a paragraph break;
-to insert a link, you use the <a href="(location of the web page to be linked)">text to appear on the page</a> tags;
-and finally, the <hr> tag inserts a horizontal rule in the page, just like this one:
