W3.CSS Sidebar



W3.CSS Vertical Navigation Bars

With side navigation, you have several options:

  • Always display the navigation pane to the left of the page content
  • Use a collapsible, "fully automatic" responsive side navigation
  • Open navigation pane over the left part of the page content
  • Open navigation pane over all of the page content
  • Slide the page content to the right when opening the navigation pane
  • Display the navigation pane on the right side instead of the left side

Always Display the Sidebar

Example

<div class="w3-sidebar w3-bar-block" style="width:25%">
  <a href="#" class="w3-bar-item w3-button">Link 1</a>
  <a href="#" class="w3-bar-item w3-button">Link 2</a>
  <a href="#" class="w3-bar-item w3-button">Link 3</a>
</div>

<div style="margin-left:25%">
... page content ...
</div>

Left & Right Side Navigation


Styling the Side Navigation

Add the w3-color class to the w3-sidebar to change the background color. If you want an active/current link, to let the user know which page he/she is on, add the w3-color class to one of the links as well:

Example

<div class="w3-sidebar w3-red">

Bordered Side Navigation

Use the w3-border class to add a border around the side navigation:

Example

<div class="w3-sidebar w3-border">
Try It Yourself »

Add the w3-border-bottom class to the links to create link dividers:

Example

<div class="w3-sidebar w3-bar-block">
  <a href="#" class="w3-bar-item w3-button w3-border-bottom">Link 1</a>
  <a href="#" class="w3-bar-item w3-button w3-border-bottom">Link 2</a>
  <a href="#" class="w3-bar-item w3-button">Link 3</a>
</div>

Use the w3-card class to display the side navigation as a card:

Example

<nav class="w3-sidebar w3-card">

Hoverable Links

When you mouse over the links inside a bar block, the background color will change to grey.

If you want a different background color on hover, use any of the w3-hover-color classes:

Example

<div class="w3-sidebar w3-bar-block">
  <a href="#" class="w3-bar-item w3-button w3-hover-black">Link 1</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-green">Link 2</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-blue">Link 3</a>
</div>
Try It Yourself »

You can turn off the default hover effect with the w3-hover-none class. This is often used when you only want to highlight text color (and not background color) on hover:

Example

<div class="w3-sidebar w3-bar-block">
  <a href="#" class="w3-bar-item w3-button w3-hover-none w3-hover-text-grey">Link 1</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-none w3-hover-text-green">Link 2</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-none w3-hover-text-teal">Link 3</a>
</div>

Side Navigation Sizes

Increased font-size (w3-large etc):

Increased padding (w3-padding etc):

Example

<div class="w3-sidebar w3-bar-block w3-large">
  <a href="#" class="w3-bar-item w3-button">Link</a>
  <a href="#" class="w3-bar-item w3-button">Link</a>
  <a href="#" class="w3-bar-item w3-button">Link</a>

Side Navigation with Icons

Example

<div class="w3-sidebar w3-bar-block w3-black" style="width:70px">
  <a href="#" class="w3-bar-item w3-button"><i class="fa fa-home"></i></a>
  <a href="#" class="w3-bar-item w3-button"><i class="fa fa-search"></i></a>
  <a href="#" class="w3-bar-item w3-button"><i class="fa fa-envelope"></i></a>
  <a href="#" class="w3-bar-item w3-button"><i class="fa fa-globe"></i></a>
</div>

Sidebar with Dropdown

Example

<div class="w3-sidebar w3-bar-block">
  <a href="#" class="w3-bar-item w3-button">Link 1</a>
  <a href="#" class="w3-bar-item w3-button">Link 2</a>
  <div class="w3-dropdown-hover">
    <button class="w3-button">Dropdown <i class="fa fa-caret-down"></i></button>
    <div class="w3-dropdown-content w3-bar-block">
      <a href="#" class="w3-bar-item w3-button">Link</a>
      <a href="#" class="w3-bar-item w3-button">Link</a>
    </div>
  </div>
<a href="#" class="w3-bar-item w3-button">Link 3</a>
</div>
Try It Yourself »

Tip: When the dropdown menu is "open", the dropdown link gets a grey background color to indicate that it is active. To override this, add a w3-hover-color class to both the "dropdown" <div> and <a>.


Sidebar with Accordion

Example

<div class="w3-sidebar w3-light-grey w3-card" style="width:200px">
  <a href="#" class="w3-bar-item w3-button">Link 1</a>
  <button class="w3-button w3-block w3-left-align" onclick="myAccFunc()">Accordion</button>
  <div id="demoAcc" class="w3-bar-block w3-hide w3-white w3-card-4">
    <a href="#" class="w3-bar-item w3-button">Link</a>
    <a href="#" class="w3-bar-item w3-button">Link</a>
  </div>
  <div class="w3-dropdown-click">
    <button class="w3-button" onclick="myDropFunc()">Dropdown</button>
    <div id="demoDrop" class="w3-dropdown-content w3-bar-block w3-white w3-card-4">
      <a href="#" class="w3-bar-item w3-button">Link</a>
      <a href="#" class="w3-bar-item w3-button">Link</a>
    </div>
  </div>
  <a href="#" class="w3-bar-item w3-button">Link 2</a>
  <a href="#" class="w3-bar-item w3-button">Link 3</a>

Sidebar Overlay

The w3-overlay class can be used to create an overlay effect when opening the sidebar. The w3-overlay class adds a black background with a 50% opacity to the "page content" - this effect will "highlight" the side navigation.

Example

<!-- Sidebar -->
<div class="w3-sidebar w3-bar-block w3-white w3-animate-left" style="display:none;z-index:4" id="mySidebar">
  <button class="w3-bar-item w3-button" onclick="w3_close()">Close</button>
  <a href="#" class="w3-bar-item w3-button">Link 1</a>
  <a href="#" class="w3-bar-item w3-button">Link 2</a>
  <a href="#" class="w3-bar-item w3-button">Link 3</a>
</div>

<!-- Overlay -->
<div class="w3-overlay" onclick="w3_close()" style="cursor:pointer"></div>

<!-- Page content -->
<button class="w3-button w3-xxlarge" onclick="w3_open()">&#9776;</button>
<div class="w3-container">
  <h1>Sidebar Overlay</h1>
  <p>Click on the "hamburger" icon to slide in the side navigation.</p>
</div>

<!-- JS to open and close sidebar with overlay effect -->
<script>
function w3_open() {
  document.getElementById("mySidebar").style.display = "block";
  document.getElementById("myOverlay").style.display = "block";
}

function w3_close() {
  document.getElementById("mySidebar").style.display = "none";
  document.getElementById("myOverlay").style.display = "none";
}
</script>

Sidebar Content

Add whatever you like inside the side navigation:

Example

<div class="w3-sidebar w3-bar-block w3-light-grey" style="width:50%">
  <div class="w3-container w3-dark-grey">
    <h4>Menu</h4>
  </div>

  <img src="img_fjords.jpg">

  <a href="#" class="w3-bar-item w3-button w3-red">Home</a>
  <a href="#" class="w3-bar-item w3-button">Projects
    <span class="w3-tag w3-red w3-round w3-right">8</span>
  </a>
  <a href="#" class="w3-bar-item w3-button">About</a>
  <a href="#" class="w3-bar-item w3-button">Contact</a>

  <div class="w3-panel w3-blue-grey w3-display-container">
    <span class="w3-button w3-display-topright">X</span>
    <p>Lorem ipsum box...</p>
  </div>
