title: Change DIV background color for all inputs in form
body: <p>I have a form with 20 input fields. Each input field is inside a DIV. I have a script that changes the background color of the DIV via keyup function along with two other DIV tags.</p>
  
  <p>Rather than duplicating the script 20 times for each DIV and Input, is it possible to re-write the script to do all DIV's and their Inputs?</p>
  
  <pre><code>$(document).ready(function(){
      $("#id").keyup(function() {
         if($("#id").val().length &gt; 0) $("#in1, #nu1, #lw1, #id").css("background-color","#2F2F2F").css("color", "#FFF");
         else {
   if($("#id").val().length == 0) $("#in1, #nu1, #lw1, #id").css("background-color","#E8E8E8").css("color", "#000");
         }
      });
  });
  </code></pre>
