CSS: Basics

Syntax

As mentioned beforehand, the CSS syntax is

element { property: value; }

After evert property:value statement, there must be a semicolon, a ";". The last statement in an element does not require a semicolon, but it is a good practice to do so anyway.

CSS ignores whatever whitespace, so you can write CSS many ways:

element{property:value;} element { property:value; } etc.

However, it is a good practice to do it the first way; it's more readable, and it's easy to organize and edit.
