window.onload = function() {
document.getElementById("btn").addEventListener("click", function() {
clicked()
}, true)
}

function clicked() {
var menu = document.getElementById("menu")
if(menu.classList.contains("menuToggle")) {
menu.classList.remove("menuToggle");
return;
}
menu.classList.add("menuToggle");
}
