响应式导航栏链接/列表按钮

如何解决响应式导航栏链接/列表按钮

我想为我的导航栏创建一个包含链接的按钮。但我不知道如何设置它，因为我（可能）粘性导航栏的代码不好。我希望此按钮出现在特定宽度之前，适用于智能手机和平板电脑。

这是我的代码：

window.onscroll = function() {
  myFunction()
};
var navbar = document.getElementById("navbar");
var sticky = navbar.offsetTop;

function myFunction() {
  if (window.pageYOffset >= sticky) {
    navbar.classList.add("sticky")
  } else {
    navbar.classList.remove("sticky");
  }
}
// When the user scrolls the page,execute myFunction
window.onscroll = function() {
  myFunction()
};
// Get the navbar
var navbar = document.getElementById("navbar");
// Get the offset position of the navbar
var sticky = navbar.offsetTop;
// Add the sticky class to the navbar when you reach its scroll position. Remove "sticky" when you leave the scroll position
function myFunction() {
  if (window.pageYOffset >= sticky) {
    navbar.classList.add("sticky")
  } else {
    navbar.classList.remove("sticky");
  }
}

#navbar {
  background: black;
  display: relative;
  overflow: hidden;
  z-index: 3;
}

#navbar a {
  display: block;
  color: white;
  text-align: center;
  text-decoration: none;
  float: right;
  margin: 18px 14px;
}

.sticky {
  position: fixed;
  top: 0;
  width: 100%;
}

<div id="navbar">
  <a href="#contact" style="margin-right: 35px;" class="animation">Contact</a>
  <a href="#ourteam" class="animation">Our Team</a>
  <a href="#events" class="animation">Events</a>
  <a href="#home" class="animation">Home</a>
</div>

你能帮我吗？
