Cascading Style Sheets II - Selectors

All CSS styles are made up of 3 parts: a selector, a property and a value. Selectors are the names that you give to your different styles, or the names of certain elements to style.

CSS selectors are a fundamental part of CSS. Selectors define which HTML elements you are going to be manipulating or styling with CSS code. In essence selectors are used to "select" the elements on an HTML page that are affected by rules.

What is a rule or a "Rule Set"? A rule or "rule set" is a CSS statement that tells the browser how it should render or display particular elements on a HTML page. A rule set has a particular syntax consisting of a selector followed by a declaration block. In my Basic CSS introduction, we got a glimpse of the rule set.
