An external style sheet is ideal when the style is applied to many pages. With an
external style sheet, you can change the look of an entire Web site by changing one file.
Each page must link to the style sheet using the <link> tag. The <link> tag goes inside the head section:
An external style sheet can be written in any text editor. The file
should not contain any html tags. Your style sheet should be saved with a
.css extension.
An example of a style sheet file is shown below:
Do not add a space between the
property value and the unit (such as margin-left:20 px). The correct way is: margin-left:20px
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
hr {color:sienna;}
p {margin-left:20px;}
p {margin-left:20px;}
body {background-image:url("images/back40.gif");}
