This article will guide you to adding hover in Bootstrap with example.

Step 1: Framework and cdn link setup

First of all, load the Bootstrap 4 framework CSS into the head tag of your webpage.

     <!-- Bootstrap CSS -->
   <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" integrity="sha384-zCbKRCUGaJDkqS1kPbPd7TveP5iyJE0EjAuZQTgFLD2ylzuqKfdKlfG/eSrtxUkn" crossorigin="anonymous"> 

Step 2: Included JS bootstrap

Now, load the Bootstrap JavaScript file before closing the body tag and done.

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
   <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

Step 3: Define its class name

After that, create the hover with a class name .thumbnail.

        <div class="regionPage">
        <section class="thumbs">
            <h3>Hover effect bootstrap - 4</h3>
            <div class="row">
                <div class="col-lg-2 col-md-3 col-sm-4 col-xs-6">
                    <a class="thumbnail" title="City" href="../asia/afghanistan.php"><img src="images/city.jpg" alt="City"></a>
                </div>
            </div>
        </section>
    </div>

Example.

Let’s look at the following example to understand how it basically works:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Hover</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" integrity="sha384-zCbKRCUGaJDkqS1kPbPd7TveP5iyJE0EjAuZQTgFLD2ylzuqKfdKlfG/eSrtxUkn" crossorigin="anonymous">
    <style>
        .thumbnail:hover {
            background-color: red;
            opacity: 0.5;
        }
    </style>
</head>

<body>
    <div class="regionPage">
        <section class="thumbs">
            <h3>Hover effect bootstrap - 4</h3>
            <div class="row">
                <div class="col-lg-2 col-md-3 col-sm-4 col-xs-6">
                    <a class="thumbnail" title="City" href="../asia/afghanistan.php"><img src="images/city.jpg" alt="City"></a>
                </div>
            </div>
        </section>
    </div>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

</body>

</html>
