HTML Advanced tutorial 19 : HTML 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
  • Internal style sheet
  • Inline styles

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="file.css" />
</head>

Internal Style Sheet
An internal style sheet can be used if one single document has a unique style. Internal styles are defined in the <head> section of an HTML page, by using the <style> tag, like this.

<head>
<style type="text/css">
body {background-color:black;}
p {color:red;}
</style>
</head>

Inline Styles
An inline style can be used if a unique style is to be applied to one single occurrence of an element. To use inline styles, use the style attribute in the relevant tag. The style attribute can contain any CSS property. For example.

<p style="color:red;margin-left:10px;">some paragraph.</p>
