Style Options

The style of the payment form can be changed by setting the style option in the wpwlOption object before the payment widget is loaded. Valid options are:

• plain

• card

<script>
    var wpwlOptions = {
        style: "card"
    }
</script>
<script async src="https://test.oppwa.com/v1/paymentWidgets.js?checkoutId={checkoutId}"></script>

Card Number and CVV placeholder styles

In order to change the style of the placeholders inside card-number and cvv, please use the option iframeStyle, according to the example below:

<script>
var wpwlOptions = {
    iframeStyles: {
        'card-number-placeholder': {
            'color': '#ff0000',
            'font-size': '16px',
            'font-family': 'monospace'
        },
            'cvv-placeholder': {
            'color': '#0000ff',
                'font-size': '16px',
                'font-family': 'Arial'
        }
    }
}</script>

CSS Reference

As you have seen above, you can override any of the form's CSS simply by adding custom CSS in your stylesheet. For advanced style we recommend using a default style of plain, however custom stylesheets can be combined with any of the default style options.

Base CSS Classes

For performance reasons, all elements have a base CSS class and individual CSS class, e.g. the credit card payment form container has a base .wpwl-container class and an individual .wpwl-container-card class to specify the card payment form container.

Container

.wpwl-container wraps the payment form. Use this to apply, for example, margins between your page elements and the payment form.

<div class="wpwl-container">
    ...
</div>

Individual classes:

.wpwl-container-card

Form

.wpwl-form styles all payment forms. Use this to change the look and feel of the payment form, including backgrounds or shadows.

<form class="wpwl-form wpwl-clearfix" action="https://test.oppwa.com/v1/checkouts/{checkoutId}/payment" method="POST" target="cnpIframe" lang="en">
    ...
</form>

Individual classes:

.wpwl-form-card

Groups

.wpwl-group wraps the label and the wrapper of the input element. Use this to style labels and inputs together, i.e. position or width.

<div class="wpwl-group">
    <div class="wpwl-label">...</div>
    <div class="wpwl-wrapper">...</div>
</div>

Individual classes:

.wpwl-group-brand

.wpwl-group-cardNumber

.wpwl-group-expiry

.wpwl-group-cardHolder

.wpwl-group-cvv

.wpwl-group-submit styles the ""Pay now" button.

.wpwl-group-button styles the buttons containing the brand

Labels

.wpwl-label holds the label of an input element.

<div class="wpwl-label">
    Card Number
</div>

Individual classes:

.wpwl-label-brand

.wpwl-label-cardNumber

.wpwl-label-expiry

.wpwl-label-cardHolder

.wpwl-label-cvv

Input and Select Wrappers

Input and select elements are wrapped in a div to gain more control over their styles, especially their width.

.wpwl-wrapper holds an input or select element. Use this to set the width of the containing input or select element.

<div class="wpwl-wrapper">
    ...
</div>

Individual classes:

.wpwl-wrapper-brand

.wpwl-wrapper-cardNumber

.wpwl-wrapper-expiry

.wpwl-wrapper-cardHolder

.wpwl-wrapper-cvv

.wpwl-wrapper-submit

Input and Select Elements

All textual <input>, <textarea>, and <select> elements have a base .wpwl-control class and are set to width: 100%; by default. The width of these elements should be set via .wpwl-wrapper.

.wpwl-control styles the borders, backgrounds or paddings of all <input> and <select> elements.

<input class="wpwl-control wpwl-control-cardNumber" name="card.number" autocomplete="off" type="tel" placeholder="Card Number">

<select class="wpwl-control wpwl-control-brand" name="paymentBrand">
    <option value="MASTER">Mastercard</option>
    <option value="VISA">Visa</option>
</select>

Individual classes:

.wpwl-control-brand

.wpwl-control-cardNumber

.wpwl-control-expiry

.wpwl-control-cardHolder

.wpwl-control-cvv

Buttons

.wpwl-button styles the submit buttons.

<button type="submit" name="pay" class="wpwl-button wpwl-button-pay">Pay now</button>

Individual classes:

.wpwl-button-pay styles the "Pay now" button.

.wpwl-button-brand styles the buttons containing a brand.

Brands

.wpwl-brand styles the brand icons.

<div class="wpwl-brand wpwl-brand-MASTER"></div>

Individual classes:

.wpwl-brand-card styles the card brands

.wpwl-brand-BRAND styles the specific brand.

Error Hints

.wpwl-has-error adds a red background, border and color to the input element and a red color to the next .wpwl-hint element.

<input autocomplete="off" type="tel" name="card.number" class="wpwl-control wpwl-control-cardNumber wpwl-has-error" placeholder="Card Number">
<div class="wpwl-hint wpwl-hint-cardNumberError">
    Invalid card number or brand
</div>

Individual classes:

.wpwl-hint-cardNumberError

.wpwl-hint-expiryError

.wpwl-hint-cardHolderError

.wpwl-hint-cvvError

Helpers

.wpwl-clearfix allows elements to contain floats without re-sorting. Assuming that .wpwl-label and .wpwl-wrapper are floated, .wpwl-group needs .wpwl-clearfix.

<div class="wpwl-group wpwl-clearfix">
    <div class="wpwl-label">...</div>
    <div class="wpwl-wrapper">...</div>
</div>
