Menu
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 can achieve this effect by using only one CSS property: box-shadow . This works by specifying the spread-radius of the box-shadow . By increasing the spread, you increase the size of the box-shadow . The goal is to make it so big, that it covers the whole page.
Method 1: Use “filter” Property to Darken Background Image in CSS. In CSS, the “filter” property is utilized to add graphical effects on HTML elements, especially on images. This property can also help in darkening the background image when its “brightness” value is added.
The opacity of the black gradient can be changed to control the amount of darkening. This can be used accordingly to darken the image as required. Example: Using an opacity of 0.5 of the background gradient to darken the image.
There is a codepen ilustrating your needs. (creating a dismissable popup and dimming the view)
HTML:

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>
