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

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>

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>
</div>
Animated Sidebar
Use any of the w3-animate-classes to fade, zoom or slide in side navigation:
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" style="display:none;z-index:5" 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"
id="myOverlay"></div>
<!-- Page content -->
<button class="w3-button w3-xxlarge"
onclick="w3_open()">☰</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_snowtops.jpg">
<a href="#"
class="w3-bar-item w3-button w3-red">Home</a>
<a href="#" class="w3-bar-item w3-button">Projects

<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
