Styling HTML with CSS

CSS was introduced with HTML 4, to provide a common way to style HTML elements.
CSS styling can be added to HTML in the following ways
  • in separate 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 styles and CSS in our 

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>

The style attribute 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>

The style attribute makes 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">This is a heading</h1>
<p>The heading above is aligned to the center of this page.</p>
</body>

</html>

The style attribute makes the old "align" attribute obsolete.

Deprecated Tags and Attributes

In HTML 4, several tags and attributes are deprecated. Deprecated means that they will not be supported in future versions of HTML and XHTML.
Remark The message is clear: Avoid using deprecated tags and attributes!
These tags and attributes should be avoided:
TagsDescription
<center>Deprecated. Defines centered content
<font> and <basefont>Deprecated. Defines HTML fonts
<s> and <strike>Deprecated. Defines strikethrough text
<u>Deprecated. Defines underlined text
AttributesDescription
alignDeprecated. Defines the alignment of text
bgcolorDeprecated. Defines the background color
colorDeprecated. Defines the text color
For all of the above: Use styles instead!
