About Card - check out the demo
From the project's README at github.com/jessepollak/card. Lightly cleaned for readability; for the full source see the upstream repo.
Card will take any credit card form and make it the best part of the checkout process (without you changing anything). Everything is created with pure CSS, HTML, and Javascript, no images required. Usage (without jQuery)
To use, you'll need to include the Card JavaScript files into your HTML, no CSS link is necessary as the JavaScript file does this for you. You can find the necessary file at and include it in your HTML like so.
```javascript var card = new Card({ // a selector or DOM element for the form where users will // be entering their information form: 'form', // required // a selector or DOM element for the container // where you want the card to appear container: '.card-wrapper', // required
formSelectors: { numberInput: 'input#number', // optional, default input[name="number"] expiryInput: 'input#expiry', // optional, default input[name="expiry"] cvcInput: 'input#cvc', // optional, default input[name="cvc"] nameInput: 'input#name' // optional - defaults input[name="name"] },
