This article will guide you to adding input spinner 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">

Step 2: Includes bootstrap library

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

<!-- Bootstrap CSS -->
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"> 
<script src="https://cdn.jsdelivr.net/npm/@popperjs/[email protected]/dist/umd/popper.min.js" integrity="sha384-IQsoLXl5PILFhosVNubq5LC7Qb9DXgDA9i+tQ8Zj3iwWAwPtgFTxbJ8NT4GN1R8p" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" integrity="sha384-Atwg2Pkwv9vp0ygtn1JAojH0nYbwNJLPhwyoVbhoPwBhjQPR5VtM2+xf0Uwh9KtT" crossorigin="anonymous"></script>

Step 3: Includes css in html page

Here we are using in css class to add plus and minus button click.

.number-input input[type="number"] {
  -webkit-appearance: textfield;
  -moz-appearance: textfield;
  appearance: textfield;
}

.number-input input[type=number]::-webkit-inner-spin-button,
.number-input input[type=number]::-webkit-outer-spin-button {
  -webkit-appearance: none;
}

.number-input {
  display: flex;
  justify-content: space-around;
  align-items: center;
}

.number-input button {
  -webkit-appearance: none;
  background-color: transparent;
  border: none;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  margin: 0;
  position: relative;
}

.number-input button:before,
.number-input button:after {
  display: inline-block;
  position: absolute;
  content: '';
  height: 2px;
  transform: translate(-50%, -50%);
}

.number-input button.plus:after {
  transform: translate(-50%, -50%) rotate(90deg);
}

.number-input input[type=number] {
  text-align: center;
}

.number-input.number-input {
  border: 1px solid #ced4da;
  width: 10rem;
  border-radius: .25rem;
}

.number-input.number-input button {
  width: 2.6rem;
  height: .7rem;
}

.number-input.number-input button.minus {
  padding-left: 10px;
}

.number-input.number-input button:before,
.number-input.number-input button:after {
  width: .7rem;
  background-color: #495057;
}

.number-input.number-input input[type=number] {
  max-width: 4rem;
  padding: .5rem;
  border: 1px solid #ced4da;
  border-width: 0 1px;
  font-size: 1rem;
  height: 2rem;
  color: #495057;
}

@media not all and (min-resolution:.001dpcm) {
  @supports (-webkit-appearance: none) and (stroke-color:transparent) {

    .number-input.def-number-input.safari_only button:before,
    .number-input.def-number-input.safari_only button:after {
      margin-top: -.3rem;
    }
  }
}

Step 4: Define its class name

After that, create the input spinner with a class name class="def-number-input number-input".

   
       <div class="def-number-input number-input">
        <button onclick="this.parentNode.querySelector('input[type=number]').stepDown()" class="minus"></button>
        <input class="quantity" min="0" name="quantity" value="1" type="number">
        <button onclick="this.parentNode.querySelector('input[type=number]').stepUp()" class="plus"></button>
      </div>
	

Example.

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

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap </title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

<style>
.number-input input[type="number"] {
  -webkit-appearance: textfield;
  -moz-appearance: textfield;
  appearance: textfield;
}

.number-input input[type=number]::-webkit-inner-spin-button,
.number-input input[type=number]::-webkit-outer-spin-button {
  -webkit-appearance: none;
}

.number-input {
  display: flex;
  justify-content: space-around;
  align-items: center;
}

.number-input button {
  -webkit-appearance: none;
  background-color: transparent;
  border: none;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  margin: 0;
  position: relative;
}

.number-input button:before,
.number-input button:after {
  display: inline-block;
  position: absolute;
  content: '';
  height: 2px;
  transform: translate(-50%, -50%);
}

.number-input button.plus:after {
  transform: translate(-50%, -50%) rotate(90deg);
}

.number-input input[type=number] {
  text-align: center;
}

.number-input.number-input {
  border: 1px solid #ced4da;
  width: 10rem;
  border-radius: .25rem;
}

.number-input.number-input button {
  width: 2.6rem;
  height: .7rem;
}

.number-input.number-input button.minus {
  padding-left: 10px;
}

.number-input.number-input button:before,
.number-input.number-input button:after {
  width: .7rem;
  background-color: #495057;
}

.number-input.number-input input[type=number] {
  max-width: 4rem;
  padding: .5rem;
  border: 1px solid #ced4da;
  border-width: 0 1px;
  font-size: 1rem;
  height: 2rem;
  color: #495057;
}

@media not all and (min-resolution:.001dpcm) {
  @supports (-webkit-appearance: none) and (stroke-color:transparent) {

    .number-input.def-number-input.safari_only button:before,
    .number-input.def-number-input.safari_only button:after {
      margin-top: -.3rem;
    }
  }
}
</style>
</head>
<body>
    <div class="def-number-input number-input safari_only">
        <button onclick="this.parentNode.querySelector('input[type=number]').stepDown()" class="minus"></button>
        <input class="quantity" min="0" name="quantity" value="1" type="number">
        <button onclick="this.parentNode.querySelector('input[type=number]').stepUp()" class="plus"></button>
      </div>
	
</body>
</html>

Check the output of the above code example.
