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.

Styling the Div Element
When styling a div element, you have to specify which element you are styling. If you are working with a div, you can optionally put div in front (if you are working with a span, then put a span, etc.). To specify an element by id, put # then the id, and to specify an element by class, put a period (a .) then the class. For example
#header{background:green;}
will make the header look something like this
The tag that was modified would be
Header Text
