How TO - Hover Tabs
Learn how to change tabs on hover, with CSS and JavaScript.
Hover Tabs
Move the mouse over one of the menu buttons to show the tab content:
London
London is the capital city of England.
Paris
Paris is the capital of France.
Tokyo
Tokyo is the capital of Japan.
Create Hoverable Vertical Tabs
Step 1) Add HTML:
Example
<div class="tab">
<button class="tablinks"
onmouseover="openCity(event,
'London')">London</button>
<button class="tablinks"
onmouseover="openCity(event,
'Paris')">Paris</button>
<button class="tablinks"
onmouseover="openCity(event,
'Tokyo')">Tokyo</button>
</div>
<div id="London" class="tabcontent">
<h3>London</h3>
<p>London is the capital city of England.</p>
</div>
<div
id="Paris" class="tabcontent">
<h3>Paris</h3>
<p>Paris
is the capital of France.</p>
</div>
<div id="Tokyo" class="tabcontent">
<h3>Tokyo</h3>
<p>Tokyo is the capital of Japan.</p>
</div>
Create buttons to open the specific
tab content. All <div> elements with class="tabcontent" are hidden by default
(with CSS & JS) - when the user move the mouse over a button - it will open the tab content
that "matches" this button.
Step 2) Add CSS:
Style the buttons and the tab content:
Example
/* Style the tab */
.tab {
float: left;
border: 1px solid #ccc;
background-color: #f1f1f1;
width: 30%;
height: 300px;
}
/* Style the buttons that are used to open the tab content */
.tab button {
display: block;
background-color: inherit;
color: black;
padding: 22px 16px;
width: 100%;
border: none;
outline: none;
text-align: left;
cursor: pointer;
}
/* Change
background color of buttons on hover */
.tab button:hover {
background-color: #ddd;
}
/* Create an active/current "tab button"
class */
.tab button.active {
background-color:
#ccc;
}
/* Style the tab content */
.tabcontent {
float: left;
padding: 0px 12px;
border: 1px solid #ccc;
width: 70%;
border-left: none;
height: 300px;
display: none;
}
Step 3) Add JavaScript:
Example
function openCity(evt, cityName) {
// Declare all
variables
var i, tabcontent, tablinks;
// Get all elements with class="tabcontent" and hide them
tabcontent
= document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
// Get all elements with class="tablinks" and remove
the class "active"
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i <
tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
// Show the current tab, and add an "active" class to
the link that opened the tab
document.getElementById(cityName).style.display = "block";
evt.currentTarget.className += " active";
}
