External CSS
With an external style sheet, you can change the look of an entire website by 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.
Example
External styles are defined within the <link> element, inside the <head> section of an HTML page:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
An external style sheet can be written in any text editor, and must be saved with a .css extension.
The external .css file should not contain any HTML tags.
Here is how the "mystyle.css" file looks like:
"mystyle.css"
body {
background-color: lightblue;}
h1 {
color: navy;
margin-left: 20px;}
how it looks:
background-color: lightblue;}
h1 {
color: navy;
margin-left: 20px;}
how it looks:
