How To Create Hoverable Tabs Using CSS And JavaScript

Create Hoverable Vertical Tabs

Step 1: Create index.html and implement below code.

<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>

<div class="clearfix"></div>

Step 2: Now implement CSS code to display tab content.

<style>
    * {box-sizing: border-box}
    body {font-family: "Lato", sans-serif;}

    /* Style the tab */
    .tab {
        float: left;
        border: 1px solid tomato;
        background-color: #f1f1f1;
        width: 30%;
        height: 300px;
    }

    /* Style the buttons inside the tab */
    .tab button {
        display: block;
        background-color: inherit;
        color: black;
        padding: 22px 16px;
        width: 100%;
        border: none;
        outline: none;
        text-align: left;
        cursor: pointer;
        font-size: 17px;
    }

    /* Change background color of buttons on hover */
    .tab button:hover {
        background-color: tomato;
    }

    /* Create an active/current "tab button" class */
    .tab button.active {
        background-color: tomato;
    }

    /* Style the tab content */
    .tabcontent {
        float: left;
        padding: 0px 12px;
        border: 1px solid tomato;
        width: 70%;
        border-left: none;
        height: 300px;
        display: none;
    }

    /* Clear floats after the tab */
    .clearfix::after {
        content: "";
        clear: both;
        display: table;
    }
</style>

Step 3: Now Implement java script to open tabs content.

<script>
    function openCity(evt, cityName) {
        var i, tabcontent, tablinks;
        tabcontent = document.getElementsByClassName("tabcontent");
        for (i = 0; i < tabcontent.length; i++) {
            tabcontent[i].style.display = "none";
        }
        tablinks = document.getElementsByClassName("tablinks");
        for (i = 0; i < tablinks.length; i++) {
            tablinks[i].className = tablinks[i].className.replace(" active", "");
        }
        document.getElementById(cityName).style.display = "block";
        evt.currentTarget.className += " active";
    }
</script>
