Abigail Rose Jenkins Jul 25, 2025 am 02:56 AM css Drop-down menu Creating a pure CSS drop-down menu does not require JavaScript. First, build an HTML structure containing nested lists; 2. Use CSS to set the main menu to horizontal layout and beautify the style; 3. Set the display of .dropdown-content to none and combine the :hover pseudo-class to hover display pull-down items; 4. To avoid the impact of floating, use ::after to clear the float and set .dropdown to relative to accurately locate the drop-down box; 5. Finally, you can improve usability and responsiveness by adding transition, focus support and media queries, thereby completing a simple and reliable pure CSS drop-down menu, ending with a complete sentence. Creating a CSS dropdown menu is straightforward and doesn't require JavaScript if you're building a simple hover-based menu. Here's how to make one step by step. 1. Basic HTML Structure Start with a simple navigation structure using an unordered list ( <ul></ul> ) and list items ( <li> ). One of the items will contain a submenu that appears on hover. <nav class="dropdown-menu"> <ul> <li><a href="#">Home</a></li> <li class="dropdown"> <a href="#" class="dropbtn">Services ▼</a> <ul class="dropdown-content"> <li><a href="#">Web Design</a></li> <li><a href="#">Development</a></li> <li><a href="#">SEO</a></li> </ul> </li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </nav> 2. Style the Main Menu Use CSS to style the top-level navigation. Make it horizontal and clean. .dropdown-menu ul { list-style: none; margin: 0; padding: 0; background-color: #333; overflow: hidden; } .dropdown-menu ul li { float: left; } .dropdown-menu ul li a { display: block; color: white; text-align: center; padding: 14px 20px; text-decoration: none; } .dropdown-menu ul li a:hover { background-color: #555; } 3. Hide and Show the Dropdown The dropdown submenu ( .dropdown-content ) should be hidden by default and appear when the user hovers over the parent item. .dropdown-content { display: none; /* Hidden by default */ position: absolute; background-color: #444; min-width: 160px; box-shadow: 0px 8px 16px rgba(0,0,0,0.2); z-index: 1; } .dropdown-content li { text-align: left; } .dropdown-content a { color: white; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content a:hover { background-color: #666; } Now, show the dropdown when hovering over the parent .dropdown : .dropdown:hover .dropdown-content { display: block; /* Show on hover */ } 4. Fix Layout and Clear Floats Since we used float: left , it's good practice to clear floats and ensure the container expands properly. .dropdown-menu ul::after { content: ""; clear: both; display: table; } You might also want to adjust positioning so the dropdown appears directly below the parent: .dropdown { position: relative; } Full Working Example (Summary) <!DOCTYPE html> <html> <head> <style> .dropdown-menu ul { list-style: none; margin: 0; padding: 0; background-color: #333; overflow: hidden; } .dropdown-menu ul li { float: left; } .dropdown-menu ul li a { display: block; color: white; text-align: center; padding: 14px 20px; text-decoration: none; } .dropdown-menu ul li a:hover { background-color: #555; } .dropdown { position: relative; } .dropdown-content { display: none; position: absolute; background-color: #444; min-width: 160px; box-shadow: 0px 8px 16px rgba(0,0,0,0.2); z-index: 1; } .dropdown-content a { color: white; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content a:hover { background-color: #666; } .dropdown:hover .dropdown-content { display: block; } .dropdown-menu ul::after { content: ""; clear: both; display: table; } </style> </head> <body> <nav class="dropdown-menu"> <ul> <li><a href="#">Home</a></li> <li class="dropdown"> <a href="#" class="dropbtn">Services ▼</a> <ul class="dropdown-content"> <li><a href="#">Web Design</a></li> <li><a href="#">Development</a></li> <li><a href="#">SEO</a></li> </ul> </li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </nav> </body> </html> Tips and Improvements<li> Use :focus and keyboard navigation for accessibility.<li> For mobile, consider using JavaScript or CSS media queries with a toggle (hamburger menu).<li> You can add transitions for a smoother appearance: .dropdown-content { opacity: 0; top: 100%; transition: opacity 0.3s; visibility: hidden; } .dropdown:hover .dropdown-content { opacity: 1; visibility: visible; } Basically, that's it — a clean, pure CSS dropdown menu that works on hover.

Creating a CSS dropdown menu is straightforward and doesn't require JavaScript if you're building a simple hover-based menu. Here's how to make one step by step.
Start with a simple navigation structure using an unordered list ( <ul></ul> ) and list items ( <li> ). One of the items will contain a submenu that appears on hover.
<ul></ul>
<li>
<nav class="dropdown-menu"> <ul> <li><a href="#">Home</a></li> <li class="dropdown"> <a href="#" class="dropbtn">Services ▼</a> <ul class="dropdown-content"> <li><a href="#">Web Design</a></li> <li><a href="#">Development</a></li> <li><a href="#">SEO</a></li> </ul> </li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </nav>
Use CSS to style the top-level navigation. Make it horizontal and clean.
.dropdown-menu ul { list-style: none; margin: 0; padding: 0; background-color: #333; overflow: hidden; } .dropdown-menu ul li { float: left; } .dropdown-menu ul li a { display: block; color: white; text-align: center; padding: 14px 20px; text-decoration: none; } .dropdown-menu ul li a:hover { background-color: #555; }
The dropdown submenu ( .dropdown-content ) should be hidden by default and appear when the user hovers over the parent item.
.dropdown-content
.dropdown-content { display: none; /* Hidden by default */ position: absolute; background-color: #444; min-width: 160px; box-shadow: 0px 8px 16px rgba(0,0,0,0.2); z-index: 1; } .dropdown-content li { text-align: left; } .dropdown-content a { color: white; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content a:hover { background-color: #666; }
Now, show the dropdown when hovering over the parent .dropdown :
.dropdown
.dropdown:hover .dropdown-content { display: block; /* Show on hover */ }
Since we used float: left , it's good practice to clear floats and ensure the container expands properly.
float: left
.dropdown-menu ul::after { content: ""; clear: both; display: table; }
You might also want to adjust positioning so the dropdown appears directly below the parent:
.dropdown { position: relative; }
<!DOCTYPE html> <html> <head> <style> .dropdown-menu ul { list-style: none; margin: 0; padding: 0; background-color: #333; overflow: hidden; } .dropdown-menu ul li { float: left; } .dropdown-menu ul li a { display: block; color: white; text-align: center; padding: 14px 20px; text-decoration: none; } .dropdown-menu ul li a:hover { background-color: #555; } .dropdown { position: relative; } .dropdown-content { display: none; position: absolute; background-color: #444; min-width: 160px; box-shadow: 0px 8px 16px rgba(0,0,0,0.2); z-index: 1; } .dropdown-content a { color: white; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content a:hover { background-color: #666; } .dropdown:hover .dropdown-content { display: block; } .dropdown-menu ul::after { content: ""; clear: both; display: table; } </style> </head> <body> <nav class="dropdown-menu"> <ul> <li><a href="#">Home</a></li> <li class="dropdown"> <a href="#" class="dropbtn">Services ▼</a> <ul class="dropdown-content"> <li><a href="#">Web Design</a></li> <li><a href="#">Development</a></li> <li><a href="#">SEO</a></li> </ul> </li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </nav> </body> </html>
:focus
.dropdown-content { opacity: 0; top: 100%; transition: opacity 0.3s; visibility: hidden; } .dropdown:hover .dropdown-content { opacity: 1; visibility: visible; }
