I am developing a project and I arrived in a part when the user click on his emoji that box appear with the display = 'block' and the body get opacity of 0.8 and only this box be without opacity, only when I apply the opacity on the body the clickuser child element is also superimposed by the note opacity :

body  {
    width: 100%;
    margin: 0 ;
    background-color: #E7E7E6;
    
}


.topo{
     position: fixed;
    background-color: white;
   width: 100%;
   top: 0;
   min-height: 56px;
   margin-top: -1px !important;
    padding: 3px;
    text-align: center;
    -webkit-box-shadow: 0px 1px 4px 0px rgba(148,146,148,0.85);
-moz-box-shadow: 0px 1px 4px 0px rgba(148,146,148,0.85);
box-shadow: 0px 1px 4px 0px rgba(148,146,148,0.85);

Issac would not be better to place an element with opacity over the body than to place opacity on the entire body ;)

The problem that if I put an element over the body will continue the same thing because the box remains a child of the body

As the div that you do not want to be transparent is direct daughter of the body, you can create a class so that all direct child elements of the body are transparent, except the div in question, using :not():

body.transparente >*:not(#clickuser){
   opacity: .5;
}

By clicking the user icon, you add the class .transparente to the body:

document.body.classList.add("transparente");

And remove by clicking again:

document.body.classList.remove("transparente");

Put as well z-index: 1; in the div #clickuser so that it does not overlap with the following elements.

Behold:

I put a red background on the user icon button to illustrate, since the image is not loaded.

var caixadeuser = document.getElementById('clickuser')
 var bonecouser = document.getElementById('user')
 bonecouser.addEventListener('click', mostrarcaixa)

 function mostrarcaixa(){


    if(caixadeuser.style.display !== 'block'){
        caixadeuser.style.display = 'block';
        document.body.classList.add("transparente");
        }

    else{
        caixadeuser.style.display = 'none'
        document.body.classList.remove("transparente");
        caixadeuser.style.transition = '1s';
    }
    

 }
