    <div id="container">
        <nav>
        <h1> Menu<span id="openIcon"> <i class="fa fa-align-justify" aria-hidden="true"></i></span></h1>
        <ul id="sidemenu" style="list-style-type:none">

Answer 1

尝试使用简单的侧边菜单

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>  
<script>

(function(){
   $('#openIcon').on('click', function(){
     $('#sidemenu').toggleClass('active');
   });
})();

#openIcon {
  cursor: pointer;
}
#sidemenu {
  left: -100%;
  position: absolute;
}
.active {
  left: 0 !important;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />
<nav>
  <h1> Menu<span id="openIcon"> <i class="fa fa-align-justify" aria-hidden="true"></i></span></h1>
  <ul id="sidemenu" style="list-style-type:none">
    <li class="list"> <a href="https://yahoo.co.in">Yahoo!!</a></li>
    <li class="list"> <a href="https://gmail.com"> GMail </a></li>
    <li class="list"> <a href= "https://twitter.com">twitter</a></li>
  </ul>
</nav>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

如果您需要全宽度菜单，请使用类似

的内容

(function(){
	var $hideElement = $('#menuDiv');
	$('#menu').on('click', function(){
		$hideElement.addClass('opend');
	});
	$('#active_menu').on('click', function(){
		$hideElement.removeClass('opend');
	});
})();

#menuDiv {
	position:fixed;
	left:-100%;
	top:0;
	width:100%;
	height:100%;
	background:#F5CFD0;
	z-index:999;
	overflow-x:hidden;
	transition-duration:05s;
	-moz-transition-duration:0.5s;
	-ms-transition-duration:0.5s;
	-webkit-transition-duration:0.5s;
}
.opend {
	left:0 !important;
}
#active_menu {
    position: absolute;
    top: 0;
    right: 20px;
    width: 100%;
    padding-top: 15px;
    text-align: right;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />
<a href="#" id="menu"><i class="fa fa-align-justify" aria-hidden="true"></i></a>
<div id="menuDiv">
	<a href="#" id="active_menu"><i class="fa fa-times" aria-hidden="true"></i></a>
	
    
</div><!-- /.menuDiv -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
