  27.                         </div>
  28.                 </div>
  29.                 <div class="col-md-6">

  32.                                 <div class="form-group">
  33.                                         <input type="number" id="yard2" placeholder="Enter number here" class="form-control"/>
  34.                                 </div>
  35.                                 <div class="form-group">

This code contains the script of the application. This code will automatically convert the foot to yard value or vice versa. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js folder.
  1. function convertToYard(){
  2.         var foot1 = document.getElementById("foot1").value;
  3.         if(foot1 != ""){
  4.                 var number = parseFloat(foot1);
  5.                 document.getElementById("yard1").value = (number*0.333333)+"yd";
  6.         }else{
  7.                 alert("Please enter something");
  8.         }
  9. }
  10.  
  11. function convertToFoot(){
  12.         var yard2 = document.getElementById("yard2").value;
  13.         if(yard2 != ""){
  14.                 var number = parseFloat(yard2);
  15.                 document.getElementById("foot2").value = (number*3)+"ft";
  16.         }else{
  17.                 alert("Please enter something");
