A CSS style has the syntax:
selector { property : value ; }
Selectors are the way that you define what is going to be styled and what isn't.
There are three basic types of selectors:
- type selectors - that select a specific tag to style
- class selectors - that select elements with an assigned class
- id selectors - that select the element on the page with that specific ID
You can apply the same style to multiple selectors through grouping.
There are some CSS properties that can affect multiple styles at once. These are called shorthand properties. They are used to speed download and lessen maintenance.
You can also comment CSS to provide information for future designers or just remind yourself what you meant when you built the styles.
