HTML Structure Explained
Let’s start with the HTML markup. This structure uses nested ul and li elements to create the dropdown hierarchy.
<link href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500;600&display=swap" rel="stylesheet">
<div class="menu-container">
<ul class="navigation">
<li><a href="#">Home</a></li>
<li><a href="#">About Us</a></li>
<li class="dropdown"><a href="#">Service</a>
<ul>
<li><a href="#">Service 1</a></li>
<li class="dropdown"><a href="#">Service 2</a>
<ul>
<li><a href="#">Service A</a></li>
<li><a href="#">Service B</a></li>
<li><a href="#">Service C</a></li>
<li><a href="#">Service D</a></li>
</ul>
</li>
<li><a href="#">Service 3</a></li>
<li><a href="#">Service 4</a></li>
</ul>
</li>
<li><a href="#">Enquiry</a></li>
<li><a href="#">Contact Us</a></li>
</ul>
</div>
CSS Styling Breakdown
Now let’s style the menu using CSS. We’ll use Flexbox for layout and absolute positioning for dropdowns.
body {
font-family: 'Poppins', sans-serif;
}
ul.navigation {
list-style: none;
padding: 0;
margin: 0;
display: flex;
flex-wrap: wrap;
}
ul.navigation li {
position: relative;
display: block;
font-size: 13px;
}
ul.navigation li > ul {
display: none;
position: absolute;
top: 100%;
left: 0;
width: 130px;
padding: 0;
}
ul.navigation li a {
text-decoration: none;
color: #000;
background: #efefef;
padding: 10px 20px;
display: block;
}
ul.navigation li:hover a {
background: #2c2c2c;
color: #fff;
}
ul.navigation li:hover > ul {
display: block;
}
ul.navigation li:hover > ul li {
width: 100%;
}
ul.navigation li:hover ul ul {
left: 100%;
top: 0;
}
ul.navigation li ul li:hover > a {
background: #efefef;
color: #000;
}
ul.navigation li.dropdown:before {
content: "";
border: 5px solid transparent;
border-top-color: #000;
position: absolute;
right: 3px;
top: 54%;
transform: translateY(-50%);
}
ul.navigation li:hover:before {
border-top-color: #fff;
}
ul.navigation li.dropdown li.dropdown:before {
border-top-color: #fff;
}
ul.navigation li.dropdown li.dropdown:hover:before {
border-top-color: #2c2c2c;
}
Responsive Considerations
This menu is horizontal and works well on desktops. For mobile responsiveness, you’d typically add media queries and toggle visibility using JavaScript or CSS checkboxes — but that’s a topic for another post.
