The default background color is white. We can change this with the style attribute. Here's how to change the default background color from white to lightgrey:
HTML file:
Displayed by browser:
<body style="background-color:lightgrey;">
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
This is a heading
This is a paragraph.
The old bgcolor attribute, supported in older versions of HTML, is no longer valid with HTML5.
