Table of contents

  • Add JavaScript in <script> tag

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

Step 1: Includes bootstrap view

To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your <head>.

    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

Step 2: Includes bootstrap library

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

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js"></script>

Step 3: Define its class name

After that, create the accordion with plus minus with a class name class="accordion" id="accordionExample".

<div class="bs-example">
    <div class="accordion" id="accordionExample">
        <div class="card">
            <div class="card-header" id="headingOne">
                <h2 class="mb-0">
                    <button type="button" class="btn btn-link" data-toggle="collapse" data-target="#collapseOne"><i class="fa fa-plus"></i> What is Bootstrp?</button>                                  
                </h2>
            </div>
            <div id="collapseOne" class="collapse" aria-labelledby="headingOne" data-parent="#accordionExample">
                <div class="card-body">
                    <p>This torrent website mainly uploads movies in Tamil as well as More languages ​​(Malayalam, Telugu, English, Hindi) on a daily basis. Not only this, you will get all the files uploaded in many file formats here. With which you have more option to Free download them.</p>
                </div>
            </div>
        </div>
        <div class="card">
            <div class="card-header" id="headingTwo">
                <h2 class="mb-0">
                    <button type="button" class="btn btn-link collapsed" data-toggle="collapse" data-target="#collapseTwo"><i class="fa fa-plus"></i> What is react?</button>
                </h2>
            </div>
            <div id="collapseTwo" class="collapse show" aria-labelledby="headingTwo" data-parent="#accordionExample">
                <div class="card-body">

            </div>
        </div>
        <div class="card">
            <div class="card-header" id="headingThree">
                <h2 class="mb-0">
                    <button type="button" class="btn btn-link collapsed" data-toggle="collapse" data-target="#collapseThree"><i class="fa fa-plus"></i> What is CSS?</button>                     
                </h2>
            </div>
            <div id="collapseThree" class="collapse" aria-labelledby="headingThree" data-parent="#accordionExample">
                <div class="card-body">

                </div>
            </div>
        </div>
    </div>
</div>

Step 5: Add JavaScript in <script> tag

Add the following JavaScript in <script> tag after the <body> tag.

<script>
    $(document).ready(function(){
        // Add minus icon for collapse element which is open by default
        $(".collapse.show").each(function(){
            $(this).prev(".card-header").find(".fa").addClass("fa-minus").removeClass("fa-plus");
        });
        
        // Toggle plus minus icon on show hide of collapse element
        $(".collapse").on('show.bs.collapse', function(){
            $(this).prev(".card-header").find(".fa").removeClass("fa-plus").addClass("fa-minus");
        }).on('hide.bs.collapse', function(){
            $(this).prev(".card-header").find(".fa").removeClass("fa-minus").addClass("fa-plus");
        });
    });
</script>
