Hi Friends 👋,

Welcome To aGuideHub! ❤️

Today, I am going to show you. How to use z-index in bootstrap with code example.

Several Boosted components utilize z-index, the CSS property that helps control layout by providing a third axis to arrange content. We utilize a default z-index scale in Boosted that’s been designed to properly layer navigation, tooltips and popovers, modals, and more

  • Framework and cdn link setup
  • Define its class name
  • Included JS bootstrap

This article will guide you to adding z-index in Bootstrap with example.

Step 1: Framework and cdn link setup

First of all, load the Bootstrap 5 framework CSS into the head tag of your webpage.

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">

Step 2: Define its class name

After that, create the justify-content with a class name .justify-content.

<div class="z">
    <div class="red" style="height:100px; width:100px; background-color:grey; position:absolute; z-index:-1;">
        image
    </div>

    <div class="fea" style="height:100px; width:100px; margin-top:20px; margin-left:20px; background-color:black; position:absolute;">
        features
    </div>
    <div class="fea" style="height:100px; width:100px; margin-top:40px; margin-left:40px; background-color:orange; position:absolute; z-index-1;">
        rest
    </div>
</div>

Step 3: Included JS bootstrap

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

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p" crossorigin="anonymous"></script>

Example.

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

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

<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <!-- CSS only -->
    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">

    <style>
        .carousel-item {
            height: 500px;
        }
    </style>
</head>

<body>
    <div class="z">
        <div class="red" style="height:100px; width:100px; background-color:grey; position:absolute; z-index:-1;">
            image
        </div>

        <div class="fea" style="height:100px; width:100px; margin-top:20px; margin-left:20px; background-color:black; position:absolute;">
            features
        </div>
        <div class="fea" style="height:100px; width:100px; margin-top:40px; margin-left:40px; background-color:orange; position:absolute; z-index-1;">
            rest
        </div>
    </div>


    <!-- JavaScript Bundle with Popper -->
    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p" crossorigin="anonymous"></script>


</body>

</html>

Check the output of the above code example.
