Show a div only once per time the user is on the site

I\'m trying to show a div element only once per time that the user is on the site. I\'ve seen multiple answers to similar questions already, but none of them seem to work...

Try this: in html: class="popupp" change to id="popupp"

and in javascript: document.getElementById("popupp").style.visibility = visible; change to document.getElementById("popupp").style.visibility = "visible";
