CSS (Cascading Style Sheets)
  • Coding option that allows webmasters to apply simple display styles to each page of a web site by setting up templates.
  • CSS can be used to redefine the look of standard HTML tags. For instance, search engines place higher value on text contained within the tags, but the default size for these tags is generally too large for modern web design. CSS can be used to redefine the size, color, font and emphasis of these tags so that webmasters can properly utilize them in search engine optimization.
