To define a style for a special type of elements, add a class attribute to the element:
<p class="error">I am different</p>
then define a style for the elements with the specific class:
Example
p.error {
color: red;}
The id Attribute
To define a specific style for one special element, add an id attribute to the element:
<p id="p01">I am different</p>
then define a style for the element with the specific id:
Example
#p01 {
color: blue;}
Note: The id of an element should be unique within a page, so the id selector is used to select one unique element!
CSS Margin
The CSS margin property defines a margin (space) outside the border:
Example
p {
border: 1px solid powderblue;
margin: 50px;}
CSS Padding
The CSS padding property defines a padding (space) between the text and the border:
Example
p {
border: 1px solid powderblue;
padding: 30px;}
CSS Border
The CSS border property defines a border around an HTML element:
Example
p {
border: 1px solid powderblue;}
CSS Fonts
The CSS color property defines the text color to be used.
The CSS font-family property defines the font to be used.
The CSS font-size property defines the text size to be used.
Example
<!DOCTYPE html>
<html>
<head>
<style>
h1 {
color: blue;
font-family: verdana;
font-size: 300%;}
p {
color: red;
font-family: courier;
font-size: 160%;}</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
External CSS
An external style sheet is used to define the style for many HTML pages.
With an external style sheet, you can change the look of an entire web site, by changing one file!
To use an external style sheet, add a link to it in the head section of the HTML page:
Example
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
An external style sheet can be written in any text editor. The file must not contain any
HTML code, and must be saved with a .css extension.
Here is how the "styles.css" looks:
body {
background-color: powderblue;}
h1 {
color: blue;}
p {
color: red;}
Internal CSS
An internal CSS is used to define a style for a single HTML page.
An internal CSS is defined in the head section of an HTML page, within a style element:
Example
<!DOCTYPE html>
<html>
<head>
<style>
body {background-color: powderblue;}
h1 {color: blue;}
p {color: red;}</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
section of an HTML page, within a
Inline CSS
An inline CSS is used to apply a unique style to a single HTML element.
An inline CSS uses the style attribute of an HTML element.
This example sets the text color of the
element to blue:
Example
<h1 style="color:blue;">This is a Blue Heading</h1>
Styling HTML with CSS
CSS stands for Cascading Style Sheets.
CSS describes how HTML elements are to be displayed on screen, paper, or in other media.
CSS saves a lot of work. It can control the layout of multiple web pages all at once.
CSS can be added to HTML elements in 3 ways:
- Inline - by using the style attribute in HTML elements.
- Internal - by using a style element in the head section.
- External - by using an external CSS file.
The most common way to add CSS, is to keep the styles in separate CSS files. However, here we will use inline and internal styling, because this is easier to demonstrate, and easier for you to try it yourself.
