HOW TO INSERT CSS IN HTML DOCUMENT


Three Ways to Insert CSS
 
There are three ways of inserting a style sheet:
  • External style sheet
  • Internal style sheet
  • Inline style

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>
·         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:
Hr
{
Color: sienna;
}
p
{
Margin-left: 20px;
}
body
{
Background-image: URL ("images/back40.gif");
}

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 of an HTML page, by using the <style> tag, like this:
<Head>
<style>
hr
{
Color: sienna;
}
p
{
Margin-left: 20px;
}
body
{
Background-image:url("images/back40.gif");
}
</style>
</head>


Inline Styles

·         An inline style loses many of the advantages of style sheets by mixing content with presentation. Use this method sparingly!
·         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: sienna; margin-left: 20px ;"> this is a paragraph. </p>
