title: Changing background cell of table depending on value
body: <p>My site reads a XML file that contains information (values) for a data-table.
  I use CSS to style the table and everything works fine.</p>
  
  <p>To get a better user-experience I wondered if it is possible to change the background color of each cell dynamically depending on its value? </p>
  
  <p>For example: </p>
  
  <p>Each cell that contains a number less then "5" has a red background color; </p>
  
  <p>each cell >= "5" has a green background color.</p>
  
  <p>My first solution on this is to use Javascript - but I want to know if there is a way to solve this with CSS-styles only?</p>
