Cascading Style Sheets are a design format that allow you to arrange your Web files efficiently without adding HTML formating tags and attributes to the document body. CSS enables you to control text formatting, set background properties, manipulate page margins and spacing, manage element alignment and decoration, and format various pages within the same site.

Inline Styles are styles applied as attributes. Inline Styles are usually entered within formatting tags. Internal Styles are styles that have blocks of CSS information usually located within the HTML document itself. External or Linked Style Sheets are separate files that are saved with a .css extension and linked to documents to which their defined styles are applied.
