I followed the following tutorial and I was finally able to add a slide in menu on my WordPress site.

However, I noticed that the body scrolls when moving up and down on my mobile phone. Can someone explain to me how I can disable body scroll when the menu is opened?

Many thanks in advance!

<script>
function openNav() {
  document.getElementById("mySidenav").style.width = "100%";
}

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
}
	
</script>
