&lt;body&gt;
  &lt;div id=&quot;#overlay&quot;&gt;
    
  &lt;/div&gt;
  &lt;div&gt; content &lt;/div&gt;
&lt;/body&gt;

//first create an element with folowing styles
#overlay {
  position: fixed; /* Sit on top of the page content */
  display: none; /* Hidden by default */
  width: 100%; /* Full width (cover the whole page) */
  height: 100%; /* Full height (cover the whole page) */
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: rgba(0,0,0,0.5); /* Black background with opacity */
  z-index: 2; /* Specify a stack order in case you're using a different order for other elements */
  cursor: pointer; /* Add a pointer on hover */
}

//then you can do
const on = () =&gt; {
  document.getElementById(&quot;overlay&quot;).style.display = &quot;block&quot;;
}

const off = () =&gt; {
  document.getElementById(&quot;overlay&quot;).style.display = &quot;none&quot;;
}

Thank you! 5
