Now create your virtual keyboard with all the required keys which you can use to type any text virtually without physical access of your keyboard.

<section class="keyboard" id="keyboard1">

Create output screen where display all the typed input’s as output.

<div class="monitor">
  <div class="screen">
    <p id="output"></p>
  </div>
</div>


CSS

Now time to styling your virtual keyboard with some awesome stylesheet which make your virtual keyboard look alike physical keyboard so that you feel like you are typing on real keyboard.

JS

Finally make your virtual keyboard actionable by add following methods.

var init = function() {  
  var shift = false;
  var caps = false;
 
  $(".key").mousedown(function() {
    // Setting the content to grab
    var content = $(this).html();
    var outputContent = $("#output").html();
 
    if (content.substr(0,4) == "<div") {
      if (shift) {
        var subDiv = $(this).find(".first-ch");
      }
      else {
        var subDiv = $(this).find(".second-ch");
      }
      content = subDiv.html();
    }
 
    // Setting special output, and then outputting
    if (content == "Backspace") {
      var stuff = outputContent;
      var x = stuff.length - 1;
 
      if (stuff.charAt(x) == ">") {
        var tagStart = stuff.lastIndexOf("<");
        $("#output").html(stuff.substr(0, tagStart));
      }
      else if (stuff.charAt(x) == ";") {
        var charStart = stuff.lastIndexOf("&");
        $("#output").html(stuff.substr(0, charStart));
      }
      else {
        $("#output").html(stuff.substr(0, x));
      }
    }
    else if (content == "Enter") {
      content = "<br />";
      $("#output").html($("#output").html() + content);
    }
    else if (content == "Tab") {
      content = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
      $("#output").html($("#output").html() + content);
    }
    else if (content == "Shift") {
      if (shift) {
        shift = false;
      }
      else {
        shift = true;
      }
    }
    else if (content == "Caps Lock") {
      if (caps) {
        caps = false;
      }
      else {
        caps = true;
      }
    }
    else if (content == "Ctrl" || content == "Alt" || content == "Win" || content == "Spl") {
 
    }
    else { // i.e. a letter
      capitalize = false;
 
      if (shift) {
        capitalize = !capitalize;
        shift = false;
      }
 
      if (caps) {
        capitalize = !capitalize;
      }
 
      if ((content.length == 1) && capitalize) {
        content = content.toUpperCase()
      }
 
      $("#output").html($("#output").html() + content);
    }
 
    outputContent = $("#output").html();
 
    // creating the automatic line break
    var sinceLastTag, relevantString, start, end, snippet;
    sinceLastTag = outputContent.lastIndexOf(">");
    relevantString = outputContent.substring(sinceLastTag).replace("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;", "1111");
    var relevantLength = relevantString.length;
 
    if (relevantLength > 1) {
        start = relevantString.indexOf("&");
        end = relevantString.indexOf(";") + 1;
        snippet = relevantString.substring(start, end);
        relevantString = relevantString.replace(snippet, "1");
    }
 
    if (relevantLength % 41 === 0 && relevantLength > 0) {
      var sweetSpot = outputContent.lastIndexOf(" ");
      var firstHalf = outputContent.substring(0, sweetSpot);
      var secondHalf = outputContent.substring(sweetSpot);
 
      $("#output").html(firstHalf + "<br />" + secondHalf);
    }
  });
};
 
$(document).ready(function() {
  init();
});
