ID selectors

ID selectors are used to select only a single item on a page.

Imported Style Sheet

Imported Style Sheet is a sheet that can be imported to (combined with) another sheet. This allows creating one main sheet containing declarations that apply to the whole site and partial sheets containing declarations that apply to specific elements (or documents) that may require additional styling.

Note that, like the padding, the margin goes completely around the contents: there are margins on the top, bottom, right, and left sides.
