Styling HTML with CSS
CSS was introduced together with HTML 4, to provide a better way to style HTML elements.
CSS can be added to HTML in the following ways:
- in Cascading Style Sheet files (CSS files)
- in the <style> element in the HTML head section
- in the style attribute in single HTML elements
Using the HTML Style Attribute
It is time consuming and not very practical to style HTML elements using the style attribute.
The preferred way to add CSS to HTML, is to put CSS syntax in separate CSS files.
However, in this HTML tutorial we will introduce you to CSS using the style attribute. This is done to simplify the examples. It also makes it easier for you to edit the code and try it yourself.
You can learn everything about CSS in our CSS Tutorial.
HTML Style Example - Background Color
The background-color property defines the background color for an element:
Example
<html>
<body style="background-color:yellow;">
<h2 style="background-color:red;">This is a heading</h2>
<p style="background-color:green;">This is a paragraph.</p>
</body>
</html>
<body style="background-color:yellow;">
<h2 style="background-color:red;">This is a heading</h2>
<p style="background-color:green;">This is a paragraph.</p>
</body>
</html>
Try it yourself »
The background-color property makes the "old" bgcolor attribute obsolete.
HTML Style Example - Font, Color and Size
The font-family, color, and font-size properties defines the font, color, and size of the text in an element:
Example
<html>
<body>
<h1 style="font-family:verdana;">A heading</h1>
<p style="font-family:arial;color:red;font-size:20px;">A paragraph.</p>
</body>
</html>
<body>
<h1 style="font-family:verdana;">A heading</h1>
<p style="font-family:arial;color:red;font-size:20px;">A paragraph.</p>
</body>
</html>
Try it yourself »
The font-family, color, and font-size properties make the old <font> tag obsolete.
HTML Style Example - Text Alignment
The text-align property specifies the horizontal alignment of text in an element:
Example
<html>
<body>
<h1 style="text-align:center;">Center-aligned heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
<body>
<h1 style="text-align:center;">Center-aligned heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
Try it yourself »
The text-align property makes the old <center> tag obsolete.
