Here is the general format for creating internal cascading styles

<head>

<style >

hr {color: sienna;}

p {font-family: Arial, Verdana, sans-serif; color: #00008B;}

body {background-color: #5F9EA0;}

</style>

</head>

How to write a style rule: CSS Syntax

I write my style rules like this to help me better organize them. I can easily find a rule to revise it when the rules are written like this:

h4 {
     font-size: 18px;
     text-align: left;
     font-style: normal;
     padding: 10px;
     font-variant: small-caps;
}

We can group various html elements together to give them the same style

p, li, dl {
     font-size: 12px;
     text-align: justify;
     line-height: 1.2em;
     margin: 35px;
}
