what is a cascading style sheet (css)?
A .css (cascading style sheet) file centrally controls the color, size, style, font, borders, padding etc of HTML elements. This means that the style of a web site can change without any change to the actual content. See the css sections for more details. Each page in that style will link to the appropriate style sheet with the following HTML: It should be kept in a folder called /styles/. See the usability section for more details.
