Where HTML begins

Every HTML document must begin with a document type declaration. The document type is needed so that the browser can determine the HTML version and render the page correctly.

For example, for an older version of HTML 4.01, the doctype looks like this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

And for the latest version of HTML, it's already much easier:

<!DOCTYPE html>

The latest version of HTML is also called HTML5. But since this version is already accepted as a standard and distributed almost everywhere, we'll just call it HTML.

index.html
style.css

HTML

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Declaring DOCTYPE</title> <link rel="stylesheet" href="style.css"> </head> <body> </body> </html>

CSS

body { margin: 0; min-height: 100vh; background-color: #f5f5f5; background-image: url("instructor.jpg"); background-position: 50% 50%; background-size: cover; background-repeat: no-repeat; }
