Create Scratch Card using JavaScript & HTML5 Canvas

Yet another code snippet to create a scratch card using JavaScript and HTML5 canvas. This Vanilla JavaScript plugin allows you to hide your coupon code or other winning code that will show on scratch. You can place any number/text behind the scratch area. Users can scratch with a cursor or touch swipe. Moreover, it shows a real-time scratching animation.

How to Create JavaScript Scratch Card

1. First of all create HTML canvas element and other necessary elements like below:

    <div class="card">
    <div class="base">Coupon Code: 123456789</div>
    <canvas id="scratch" width="300" height="60"></canvas>
    </div>

2. After that, style scratch card with CSS.

    .card{
         width: 300px;
         height: 60px;
         position: relative;
         box-shadow: 1px 2px 6px rgba(0, 0, 0, 0.2);
        }    
        
      .base, #scratch {
        cursor: default;
        height: 60px;
        width: 300px;
          position: absolute;
          top: 0;
          left: 0;
          cursor: grabbing;
      }
      .base {
        line-height: 60px;
        text-align: center;
      }
      #scratch {
        -webkit-tap-highlight-color: rgba(0, 0, 0, 0); 
        -webkit-touch-callout: none;
        -webkit-user-select: none;
      }

3. Finally, load the scratch card JS file into your HTML document and done.
