Using CSS element type selectors
An element type selector matches elements of the corresponding type — for example, the <p>, <span>, and <div> tags. It's generally considered poor practice to apply fine detail changes with a type selector alone. Elements like <div> are quite generic, and they hold all kinds of content that you usually want to style differently.
A common use case for element type selectors is the body text, as there can only be one <body> tag on any given page. You can use it to set the defaults for the whole page. For example:
body {
padding: 0;
margin: 0;
width: 100%;
height: 100%;
}
