    Here's a plain-JavaScript example:

    var modal = document.getElementById('modal');
var shade = document.getElementById('shade');
document.getElementById('start').onclick = function() {
  modal.style.display = shade.style.display = 'block';
};
document.getElementById('close').onclick = function() {
  modal.style.display = shade.style.display = 'none';
};

// This code is a workaround for IE6's lack of support for the
// position: fixed style.
//
if (!('maxHeight' in document.body.style)) {
  function modalsize() {
    var top = document.documentElement.scrollTop;
    var winsize = document.documentElement.offsetHeight;
    var docsize = document.documentElement.scrollHeight;
    shade.style.height = Math.max(winsize, docsize) + 'px';
    modal.style.top = top + Math.floor(winsize / 3) + 'px';
  };
  modal.style.position = shade.style.position = 'absolute';
  window.onscroll = window.onresize = modalsize;
  modalsize();
}
    body {
  margin: 0;
}

#shade,
#modal {
  display: none;
}

#shade {
  position: fixed;
  z-index: 100;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

#modal {
  position: fixed;
  z-index: 101;
  top: 33%;
  left: 25%;
  width: 50%;
}

#shade {
  background: silver;
  opacity: 0.5;
  filter: alpha(opacity=50);
}
    <div id="shade"></div>
<div id="modal">
  <textarea rows="5" cols="25"></textarea>
  <button id="close">Close</button>
</div>

<p>
  <button id="start">Start</button>
</p>

    There are various improvements you can make from there, such as iframe hacks to fix IE z-indexing, or encapsulating it in a reusable object, but that's the basic way it's done.

    jQueryUI has a modal dialog plugin. It won't release control simply by clicking the background, as you requested: http://jqueryui.com/demos/dialog/#modal

    <a href="#" class="showModal">Show Modal Box</a>
<div id="modalContents" style="display:none;">
  <textarea>Hello World</textarea>
</div>

    --

    $(".showModal").click(function(e){
  e.preventDefault();
  $("#modalContents").dialog({bgiframe: true, height: 140, modal: true});
});

    you can also use native HTML5.1 dailog. currently dialog element is only supported in Chrome 37+, Safari 6+ and Opera 24+.

    var dailog = document.getElementById("dialog"); 

function openModal() { 
   // dailog.show(); 
      dailog.showModal();
} 

function closeModal() { 
    dailog.close(); 
} 
    #dialog{width:300px;}
.right{float:right}
    <button onclick="openModal()">Show dialog</button>


<dialog id="dialog">This is a dialog window<br/><br/><br/>
<button onclick="closeModal()" class="right">Close</button>
</dialog>

    I think the below code will help you out

    <!DOCTYPE html>
<html>
<title>login modal</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">
<body>

<div class="w3-container">
  <h2>Login Modal</h2>
  <button onclick="document.getElementById('id01').style.display='block'" class="w3-button w3-green w3-large">Login</button>

  <div id="id01" class="w3-modal">
    <div class="w3-modal-content w3-card-4 w3-animate-zoom" style="max-width:600px">

      <div class="w3-center"><br>
        <span onclick="document.getElementById('id01').style.display='none'" class="w3-button w3-xlarge w3-hover-red w3-display-topright" title="Close Modal">&times;</span>
        
      </div>

      <form class="w3-container" action="/action_page.php">
        <div class="w3-section">
          <label><b>Username</b></label>
          <input class="w3-input w3-border w3-margin-bottom" type="text" placeholder="Enter Username" name="usrname" required>
          <label><b>Password</b></label>
          <input class="w3-input w3-border" type="password" placeholder="Enter Password" name="psw" required>
          <button class="w3-button w3-block w3-green w3-section w3-padding" type="submit">Login</button>
          <input class="w3-check w3-margin-top" type="checkbox" checked="checked"> Remember me
        </div>
      </form>

      <div class="w3-container w3-border-top w3-padding-16 w3-light-grey">
        <button onclick="document.getElementById('id01').style.display='none'" type="button" class="w3-button w3-red">Cancel</button>
        <span class="w3-right w3-padding w3-hide-small">Forgot <a href="#">password?</a></span>
      </div>

    </div>
  </div>
</div>
            
</body>
</html>

    a Modal window by definition requires action to be taken by the user before it can be returned to the main window. So what you are looking for is not a modal but a window.
