Tạo menu responsive đơn giản cho website

Hello các bạn, chào mừng quay lại với Tôi Viết Code.
Hôm nay mình sẽ chia sẻ cho các bạn một dạng Menu Repsonsive đơn giản mà không kém phần sang trọng hoàn toàn bằng html và css cho website. Let's go!

Bước 1:

Thêm code dưới vào phần bạn muốn đặt menu:

<nav id='navigation' itemscope='itemscope' itemtype='http://schema.org/SiteNavigationElement'>
<input type='checkbox'/>
<label><i class='fa fa-bars' style='font-size:16px;color:#fff'></i><b style='font-size:16px;color:#fff'> MENU</b></label>
<ul>
<li><a href='/'>Trang chủ</a></li>
<li><a href='#'>Menu 1</a></li>
<li><a href='#'>Menu 2</a></li>
<li><a href='#'>Menu 3</a></li>
<li><a href='#'>Menu 4</a></li>
<li><a href='#'>Menu 5</a></li>
<li><a href='#'>Menu 6</a></li>
<li><a href='#'>Menu 7</a></li>
<!-- Search -->
<div class='search' id='data-search'>
<a class='search-btn' href='#search'>
<i class='fa fa-search'></i>
<i class='fa fa-times'></i>
</a>
<div class='unstyled-list search-menu'>
<div id='search-box-pc'>
<form action='/search' id='search-form-pc' method='get' target='_top'>
<input id='search-text-pc' name='q' placeholder='Tìm kiếm...' type='text'/>
</form>
</div>
</div>
</div>
<script type='text/javascript'>
(function(){window.Menu=function(){function a(a){this.nav=a,this.menubtn=$(".search-btn",this.nav),this.menubtn.on("click",function(a){return function(b){return a.nav.toggleClass("active"),!1}}(this))}return a.init=function(){return $("#data-search").each(function(b,c){return new a($(c))})},a}(),$(function(){if($("#data-search").length)return Menu.init()})}).call(this);
</script>
</ul>
</nav>

Bước 2:

Thêm CSS vào thẻ style
