Selector (Body) - Property (Line - Height) - Value (2px)

Colon separates the property from the value. A semi colon is used after the value

Attributes can be added to opening tags. Such as, and "id" or ".class". "id" is unique, as only one can ever be used on a page, but a ".class" can be used multiple times. "id" is far more powerful than a class, and will always outweigh it.

Margine rule when applying 4 different rules:
1st value  = top
2nd value = right
3rd value = bottom
4th value = left

If you put in a single value top and bottom will be effected. Auto tag can be used to make a website sit in the middle of page.
