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
Tip: You can learn much more about CSS in our CSS Tutorial.
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
<h1> element to blue:Example
<h1 style="color:blue;">This is a Blue Heading</h1>
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>
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>
Here is how the "styles.css" looks:
body {
background-color: powderblue;}
h1 {
color: blue;}
p {
color: red;}
CSS Fonts
The CSScolor 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>
CSS Border
The CSSborder property defines a border around an HTML element:Example
p {
border: 1px
solid powderblue;}
CSS Padding
The CSSpadding property defines a padding (space) between
the text and the border:Example
p {
border: 1px
solid powderblue;
padding: 30px;}
CSS Margin
The CSSmargin property defines a margin (space) outside the border:Example
p {
border: 1px
solid powderblue;
margin: 50px;
}
The id Attribute
To define a specific style for one special element, add anid attribute to the element:
<p id="p01">I am different</p>
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!
The class Attribute
To define a style for special types of elements, add aclass attribute to the element:
<p class="error">I am different</p>
Example
p.error {
color: red;}
External References
External style sheets can be referenced with a full URL or with a path relative to the current web page.This example uses a full URL to link to a style sheet:
Example
<link rel="stylesheet" href="https://teachincal web /html/styles.css">
Example
<link rel="stylesheet" href="/html/styles.css">
Example
<link rel="stylesheet" href="styles.css">
You can read more about file paths in the chapter HTML
