CSS Styles
Three Ways to Insert CSS
There are three ways of inserting a style sheet:
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.
-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:
Example:
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
<link rel="stylesheet" type="text/css" href="mystyle.css">
</head>
body {
background-color: lightblue;}
h1 {
color: navy;
margin-left: 20px;}
background-color: lightblue;}
h1 {
color: navy;
margin-left: 20px;}
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>
<style>
body {
background-color: linen;}
h1 {
color: maroon;
margin-left: 40px;} </style>
</head>
Inline Styles
- 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>
