Mega Site Navigation với CSS3 và jQuery

HTML

Chúng ta tạo khung chuẩn html với 4 phần chính như sau :

<header class="cd-main-header">
 
    <ul class="cd-header-buttons">
        <li><a class="cd-search-trigger" href="#cd-search">Search<span></span></a></li>
        <li><a class="cd-nav-trigger" href="#cd-primary-nav">Menu<span></span></a></li>
    </ul> <!-- cd-header-buttons -->
</header>
 
<main class="cd-main-content">
    <!-- your content here -->
 
    <div class="cd-overlay"></div>
</main>
 
<nav class="cd-nav">
    <ul id="cd-primary-nav" class="cd-primary-nav is-fixed">
        <li class="has-children">
            <a href="#0">Clothing</a>
 
            <ul class="cd-secondary-nav is-hidden">
                <li class="go-back"><a href="#0">Menu</a></li>
                <li class="see-all"><a href="#0">All Clothing</a></li>
                <li class="has-children">
                    <a href="#0">Accessories</a>
 
                    <ul class="is-hidden">
                        <li class="go-back"><a href="#0">Clothing</a></li>
                        <li class="see-all"><a href="#0">All Accessories</a></li>
                        <li class="has-children">
                            <a href="#0">Beanies</a>
 
                            <ul class="is-hidden">
                                <li class="go-back"><a href="#0">Accessories</a></li>
                                <li class="see-all"><a href="#0">All Benies</a></li>

                                <li><a href="#0">Scarves</a></li>
                            </ul>
                        </li>
                        <li><!-- ... --></li>
                    </ul>
                </li>
 
                <li><!-- ... --></li>
                <li><!-- ... --></li>
                <li><!-- ... --></li>
            </ul>
        </li>
 
        <li class="has-children">
            <!-- ... -->
        </li>
 
        <li class="has-children">
            <!-- ... -->
        </li>
 
        <li><a href="#0">Standard</a></li>
    </ul> <!-- primary-nav -->
</nav> <!-- cd-nav -->
 
<div id="cd-search" class="cd-search">
    <form>
        <input type="search" placeholder="Search...">
    </form>
</div>

CSS

Sau đó các bạn định dạng menu với đoạn css sau :

@media only screen and (max-width: 1169px) {
  body.nav-on-left.overflow-hidden {
    overflow: hidden;
  }
}
 
a {
  color: #69aa6f;
  text-decoration: none;
}
 
img {
  /* make images responsive */
  max-width: 100%;
}
 
input {
  font-family: sans-serif;
  font-size: 1.6rem;
}
 
input[type="search"]::-ms-clear {
  /* removes close icon - IE */
  display: none;
}
 
input[type="search"]::-webkit-search-decoration,
input[type="search"]::-webkit-search-cancel-button,
input[type="search"]::-webkit-search-results-button,
input[type="search"]::-webkit-search-results-decoration {

}
