我尝试了下面的代码，但它使切换按钮消失了。

#content {
    position: fixed;
    z-index: -1;
}

我希望边栏像this上的

谢谢。

希望这会有所帮助。已添加

#sidebar {
    position: fixed;
    top:0;
    bottom:0;
    z-index:1;
}

并在CSS下方添加叠加层

.overlay{
  display:block;
  position:fixed;
  top:0;
  left:0;
  right:0;
  bottom:0;
  background-color:rgba(0,0,0,0.5)
}


$(document).ready(function() {
  $('#sidebarCollapse').on('click', function() {
    $('#sidebar').toggleClass('active');
    $('.overlay').toggle();
  });

  $('.overlay').click(function() {
    $('#sidebar').toggleClass('active');
    $('.overlay').toggle();
  });
});
