A CSS is made up of two parts: the selector and declaration. The selector states which tag the rule applies. The declaration stats what happens when the rule is applied.
The declaration is made up of two elements: a property and value. A declaration must end with a semicolon.
Multiple declarations can be contained in a single rule.
Multiple selectors can be contained in a single rule. A comma must be used after each selector except the last.
h1, h2, h3 {color:red; font-weight:bold;}
Multiple rules can be applied to the same selector.
h1, h2, h3 {color:red; font-weight:bold;} h3 {font-style:italic;}
