Making a Sliding Side Navigation Menu for Responsive Designs

This tutorial shows you how to build a responsive expandable side navigation menu using JavaScript and CSS. The final result is a sleek, modern menu.

Here's a live demo:

1. HTML Structure:

Start by adding the HTML for the side menu:

<div class="sidenav" id="sideNavigation">
  <a class="close-btn" href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">×</a>
  <a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">About</a>
  <a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">Features</a>
  <a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">Contact Us</a>
</div>

<nav class="topnav">
  <a class="ham-icon" href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">
    <svg height="30" id="icoOpen" width="30">
      <path d="M0,5 30,5" stroke="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b000" stroke-width="5"></path>
      <path d="M0,14 30,14" stroke="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b000" stroke-width="5"></path>
      <path d="M0,23 30,23" stroke="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b000" stroke-width="5"></path>
    </svg>
  </a>
</nav>

<main id="main">
  <h1>This Side Navigation Menu Looks Good!</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
</main>

This sets up the side menu (sidenav), a hamburger icon (ham-icon) to open it, a close button (close-btn), and the main content area (main).

2. JavaScript Functionality:

This JavaScript handles the menu's open and close actions:

document.querySelector("a.ham-icon").addEventListener("click", function(event){
  document.getElementById("sideNavigation").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
});

document.querySelector("a.close-btn").addEventListener("click", function(event){
  document.getElementById("sideNavigation").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
});

Clicking the hamburger icon expands the menu; clicking the close button collapses it.

3. CSS Styling:

The CSS styles the menu and its animation:

https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bmain {
  transition: margin-left 0.4s cubic-bezier(0.18, 0.89, 0.32, 1.28);
  padding: 20px;
  width: 100%;
}

body {
  overflow-x: hidden;
}

a svg {
  transition: all 0.5s ease;
}

a svg:hover {
  transform: rotate(180deg);
}

@media screen and (max-height: 480px) {
  .sidenav {
    padding-top: 3rem;
  }
  .sidenav a {
    font-size: 1.5rem;
  }
}

This CSS provides the smooth slide animation, handles overflow, and adds responsiveness for smaller screens. The overflow-x: hidden; on the body prevents horizontal scrollbars.

4. Removing the Slide Animation (Optional):

To remove the slide animation, set the transition properties to 0s in your CSS:

.sidenav {
  transition: 0s;
}

https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bmain {
  transition: margin-left 0s;
}

This makes the menu appear and disappear instantly.

Conclusion:

This simple yet effective side navigation menu is easily customizable and adaptable to various design needs. Consider using a CSS framework like Bootstrap or Bulma for more advanced styling options. Thanks to Monty Shokeen for his contributions!
