The HTML Style Attribute
Setting the style of an HTML element can be done with the style attribute. The HTML style attribute has the following syntax: [S1]
<tagname style="property:value;">
The property is a CSS property, and the value is a CSS value. [S1]
Background Color
The CSS background-color property defines the background color for an HTML element. Set the background color for the whole page: [S1]
<body style="background-color:powderblue;">
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
Set background color for two different elements: [S1]
<body>
<h1 style="background-color:powderblue;">This is a heading</h1>
<p style="background-color:tomato;">This is a paragraph.</p>
</body>
Text Color
The CSS color property defines the text color for an HTML element: [S1]
<h1 style="color:blue;">This is a heading</h1>
<p style="color:red;">This is a paragraph.</p>
Fonts
The CSS font-family property defines the font to be used for an HTML element: [S1]
<h1 style="font-family:verdana;">This is a heading</h1>
<p style="font-family:courier;">This is a paragraph.</p>
Text Size
The CSS font-size property defines the text size for an HTML element: [S1]
<h1 style="font-size:300%;">This is a heading</h1>
<p style="font-size:160%;">This is a paragraph.</p>
Text Alignment
The CSS text-align property defines the horizontal text alignment for an HTML element: [S1]
