CSS BASICS
The selector points to the HTML element you want to style.
The declaration block contains one or more declarations separated
by semicolons.
Each declaration includes a CSS property name and a value,
separated by a colon.
Multiple CSS declarations are separated with semicolons, and
declaration blocks are surrounded by curly brace

changing just one file!
Each HTML page must include a reference to the external style sheet file inside the
<link> element, inside the head section.

HTML page:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="mystyle.css">
</head>
<body>
