html - CSS Nav 溢出容器

Question

我有一个不响应容器的 css 导航。在 JSFiddle here一切正常。当我把它放在网站上时 here移动菜单下 zipper 接转到包装器的右上角，不会留在容器中。如果缩小屏幕，您会看到。目前在网站上它位于标题部分之外，因为我认为可能存在代码冲突。谢谢

CSS

  display: none;
  position: absolute;
  top: 0;
  right: 0;
  background: $nav-background;
  height: $nav-height;

}
@media only screen and (max-width: $breakpoint) {
  // Hamburger nav visible on mobile only
