Cascading Style Sheets.
The coding that styles the HTML of a listing. It defines size, color, font and many other features of a design. The beauty of CSS is that once you have defined the style once many elements can use that same style. e.g. <style>.redText{color:redl;}</style> would make any HTML with the redText class have red text.
