Inline Style

An inline style may be used to apply a unique style for a single element.

To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property.

The example below shows how to change the color and the left margin of a <h1> element:

Example

<h1 style=”color:blue;margin-left:30px;”>This is a heading</h1>
Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly.

Internal Style Sheet

An internal style sheet may be used if one single page has a unique style.

Internal styles are defined within the <style> element, inside the <head> section of an HTML page:

Example

<head>
<style>
body {
background-color: linen;
}h1 {
color: maroon;
margin-left: 40px;
}
</style>
</head>

External Style Sheet

With an external style sheet, you can change the look of an entire website by changing just one file!

Each page must include a reference to the external style sheet file inside the <link> element. The <link> element goes inside the <head> section:

Example

<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. The style sheet file must be saved with a .css extension.

Here is how the “mystyle.css” looks:

body {
background-color: lightblue;
}h1 {
color: navy;
margin-left: 20px;
}
