Hello

module 'html box pro' allows to use javascript code.

With Javascript you can check if cookie exists or what is the value of cookie (stored string in cookie).

in context of your case (cookie name is 'cokiebar') you can use code like:

<script>

function getCookie(cname) {

  var name = cname + "=";

  var decodedCookie = decodeURIComponent(document.cookie);

  var ca = decodedCookie.split(';');

  for(var i = 0; i <ca.length; i++) {

    var c = ca[i];

    while (c.charAt(0) == ' ') {

      c = c.substring(1);

    }

    if (c.indexOf(name) == 0) {

      return c.substring(name.length, c.length);

    }

  }

  return "";

}

if (getCookie('cokiebar') == 'hide')
{
// execute something here
}

</script>
