const links = document.querySelectorAll(".list");


burger.addEventListener("click", () => {
  navLinks.classList.toggle("open");
});
* {
  margin: 0px;
  padding: 0;
}

body {
  font-family: cursive, sans-serif, fantasy;
  background-color: #f3f3f4
}

nav {
  height: 12vh;
  background-color: #0303;
  display: block;
}

.item-menu {
  display: flex;
  list-style: none;
  justify-content: space-around;
  align-items: center;
  width: 50%;
  height: 100%;
  margin-left: auto;
  cursor: pointer;
}

.a
/* menu words */

{
  text-decoration: none;
  list-style: none;
  color: black;
}

My problem:

Well, it looks like the button does not work properly and I don't understand why. They told me the script is not loaded and to put it at the end of the body and already was. I tried to change some classes, to add more classes, to do a function....nothing of the above worked...

Please I need help...I'm almost on the point of a breakdown :)) =)) Maybe coding is not for me :X


Solution

  • in the querySelector of 'burger' set it to const burger = document.querySelector("#burger"); it's an id so we use '#' the dot '.' is for the class
