Tabbed Navigation
Tabbed navigation is a way to navigate around a website.
Normally, tabbed navigation uses navigation buttons (tabs) arranged together
with the selected tab highlighted.
This example uses elements with the same class name ("city" in our example)
, and changes the style between display:none and
display:block to hide and display different content:
Example
<div id="London" class="city">
<h2>London</h2>
<p>London is the capital
of England.</p>
</div>
<div id="Paris" class="city" style="display:none">
<h2>Paris</h2>
<p>Paris is the capital of France.</p>
</div>
<div
id="Tokyo" class="city" style="display:none">
<h2>Tokyo</h2>
<p>Tokyo is the capital of Japan.</p>
</div>
And some clickable buttons to open the tabbed content:
Example
<div class="w3-bar w3-black">
<button class="w3-bar-item w3-button"
onclick="openCity('London')">London</button>
<button
class="w3-bar-item w3-button" onclick="openCity('Paris')">Paris</button>
<button class="w3-bar-item w3-button" onclick="openCity('Tokyo')">Tokyo</button>
</div>And a JavaScript to do the job:
Example
function openCity(cityName) {
var i;
var x = document.getElementsByClassName("city");
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
document.getElementById(cityName).style.display = "block";
}

JavaScript Explained
The openCity() function is called when the user clicks on one of the buttons in the menu.
The function hides all elements with the class name "city" (display="none"),
and displays the element with the given city name (display="block");
googletag.cmd.push(function() { googletag.display('div-gpt-ad-1493883843099-0'); });
Closable Tabs
London
London is the capital city of England.
Paris
Paris is the capital of France.
Tokyo
Tokyo is the capital of Japan.
To close a tab, add onclick="this.parentElement.style.display='none'"
to an element inside the tab container:
Example
<div id="London" class="w3-display-container">
<span onclick="this.parentElement.style.display='none'"
class="w3-button w3-display-topright">X</span>
<h2>London</h2>
<p>London is the capital city of England.</p>
</div>

Active/Current Tab
To highlight the current tab/page the user is on, use JavaScript
and add a color class to the active link. In the example below, we have added a "tablink"
class to each link. That way, it is easy to get all links that is associated
with tabs, and give the current tab link a "w3-red" class, to highlight it:
Example
function openCity(evt, cityName) {
var i, x, tablinks;
x = document.getElementsByClassName("city");
for (i =
0; i < x.length; i++) {
x[i].style.display
= "none";
}
tablinks =
document.getElementsByClassName("tablink");
for (i =
0; i < x.length; i++) {
tablinks[i].className =
tablinks[i].className.replace(" w3-red", "");
}
document.getElementById(cityName).style.display =
"block";
evt.currentTarget.className += "
w3-red";
}

content:

Tabbed Image Gallery
Click on an image:
openImg("Nature");
function openImg(imgName) {
var i, x;
x = document.getElementsByClassName("picture");
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
document.getElementById(imgName).style.display = "block";
}
Example
<a href="javascript:void(0)" class="w3-hover-opacity" onclick="openImg('Nature');">
<img src="img_nature.jpg" alt="Nature">
</a>
<div id="Nature" class="picture w3-display-container">
<img
src="img_nature_wide.jpg" alt="Nature" style="width:100%">
<span onclick="this.parentElement.style.display='none'"
class="w3-display-topright">×</span>

Tabs in a Grid
Using tabs in a third column layout. Note that we add a bottom border to the active tab, instead of a background color:

x[i].style.display = "none";
}
document.getElementById(cityn).style.display = "block";
