Tabs (Tabulators)
Tabs are perfect for single page web applications, or for web pages capable of displaying different subjects.
Just create many elements with the same class name:
Example
<div id="London" class="city">
<h2>London</h2>
<p>London is the capital
city of England.</p>
</div>
<div id="Paris" class="city">
<h2>Paris</h2>
<p>Paris is the capital of France.</p>
</div>
<div
id="Tokyo" class="city">
<h2>Tokyo</h2>
<p>Tokyo is the capital of Japan.</p>
</div>
Then add some clickable buttons to open the content (single buttons, navigation bar, sidenav, etc..):
Example
<ul class="w3-navbar">
<li><a href="#" onclick="openCity('London')">London</a></li>
<li><a href="#" onclick="openCity('Paris')">Paris</a></li>
<li><a href="#" onclick="openCity('Tokyo')">Tokyo</a></li>
</ul>
And add a JavaScript to select the elements:
Example
openCity("London");
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
First, call openCity() to open "London" (id="London).
Then call open City() with a different city name (id="Paris) when the user clicks on one of the buttons in the menu.
The openCity() function hides all elements (display="none") with the class name "city", and displays the element (display="block") with the given city id.
Active/Current Tab
If you want to highlight the current tab/page the user is on, use JavaScript and add a specific color class to the current tab 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";
}
