With HTML 4.0 all formatting can be moved out
of the HTML document and into a separate style sheet.
How to Use Styles
When a browser reads a style sheet, it will format the
document according to it. There are three ways of inserting a
style sheet:
External Style Sheet
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.
<head>
<link rel="stylesheet" type="text/css"
href="mystyle.css">
</head>
|
Internal Style Sheet
An internal style sheet should be used when a single document
has a unique style. You define internal styles in the head
section with the <style> tag.
<head>
<style type="text/css">
body {background-color: red}
p {margin-left: 20px}
</style>
</head>
|
Inline Styles
An inline style should be used when a unique style is to be
applied to a single occurrence of an element.
To use inline styles you use the style attribute in the
relevant tag. The style attribute can contain any CSS property.
The example shows how to change the color and the left margin of
a paragraph:
<p style="color: red; margin-left: 20px">
This is a paragraph
</p>
