External Style Sheet.
An external style sheet is simply a text file containing a list of CSS. The file is saved with a .css extension and saved to any directory that can be accessed by the web pages using it. Unlike embedded style sheets, the CSS rules sets do not have to be wrapped in the <style>...</style> tags.
