How do i darken the whole page? ( html )

When i use an other div to do it, it will not affect other dom classes, so i have to modify each dom class when i want the whole page to get darker.

Is there a way to overlap the whole document with a gray transparent plane?

You will need to show an overlay div

<div id="overlay"></div>

Make it position fixed 

#overlay {
  background-color: rgba(0,0,0,0.5);
  position:fixed;
  left:0;
  top: 0;
  width:100%;
  height:100%;
}

and make it visible when you want to darken the page, here is how you do it

$(function(){
  //Am hiding the overlay after 2 sec
  $("#overlay").delay(3000).hide(200);
})
 #overlay {
      background-color: rgba(0,0,0,0.5);
      position:fixed;
      left:0;
      top: 0;
      width:100%;
      height:100%;
    }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<body>
  <div id="overlay"></div>
  <h1>My Awesome Page</h1>
</body>

You can add a background-color to your body with css:

#overlay {
    background-color: rgba(0,0,0,0.5); /* your color */
    width: 100%;
    height: 100%;
    position: fixed;
    top: 0;
    left: 0;
}

There is a codepen ilustrating your needs. (creating a dismissable popup and dimming the view)

HTML:

<div class="wrapper">
  <button class="btn btn-success dim">Dim the page!</button>
  <div class="dimmer">
    <span class="exit">&times;</span>
  </div>
  <div class="content">

  </div>
</div>

CSS:

.wrapper {
  padding: 2.5em;
  margin: 0 auto;
  width: 80%;
}

.dimmer {
  display: none;
    background: #000;
    opacity: 0.5;
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    z-index: 100;
}

.dim {
  display: block;
  margin: 2em auto;
  z-index: 200;
}

.exit {
  font-size: 100px;
  color: red;
  position: absolute;
  top: 2px;
  left: 2px;
  opacity: 1;
  cursor: pointer;
}

Javascript:

$(function() {
  var dimmerButton = $('.dim');
  var dimmer = $('.dimmer');
  var exit = $('.exit');
  dimmerButton.on('click', function() {
    dimmer.show();
  });
  exit.on('click', function() {
    dimmer.hide();
  });
});
