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:
  • Inline - using the style attribute in HTML elements
  • Internal - using the <style> element in the <head> section
  • External - using an external CSS file
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.

Inline Styles
An inline style can be used if a unique style is to be applied to one single occurrence of an element.
To use inline styles, use the style attribute in the relevant tag. The style attribute can contain any CSS property. The example below shows how to change the text color and the left margin of a paragraph:
<p style="color:blue;margin-left:20px;">This is a paragraph.</p>

HTML Style Example - Background Color
The background-color property defines the background color for an element:
<!DOCTYPE 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>

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:
<!DOCTYPE html>

<h1 style="font-family:verdana;">A heading</h1>
<p style="font-family:arial;color:red;font-size:20px;">A paragraph.</p>

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:
<!DOCTYPE html>

<h1 style="text-align:center;">Center-aligned heading</h1>
<p>This is a paragraph.</p>

The text-align property makes the old <center> tag obsolete.

Internal Style Sheet
An internal style sheet can be used if one single document has a unique style. Internal styles are defined in the <head> section of an HTML page, by using the <style> tag, like this:
<style type="text/css">
body {background-color:yellow;}
p {color:blue;}

External Style Sheet
An external style sheet is ideal when the style is applied to many pages. With an external style sheet, you can change the look of an entire Web site by changing one file. Each page must link to the style sheet using the <link> tag. The <link> tag goes inside the <head> section:
<link rel="stylesheet" type="text/css" href="mystyle.css" />

HTML Style Tags
Defines style information for a document
Defines the relationship between a document and an external resource

Deprecated Tags and Attributes
In HTML 4, several tags and attributes were used to style documents. These tags are not supported in newer versions of HTML.
Avoid using the elements <font>, <center>, and <strike> and the attributes color and bgcolor.
