Customization

Fields styling

To customize your secure fields with styles you have to add css object into your field initialization method to generate a standalone CSS.

What we support:

• Regular CSS properties

• Placeholders

• Generic Web Fonts and @font-face property

• Pseudo-classes (eg. :hover, :focus)

• Media queries (media query condition is calculated based on the iframe width, not on the parent window)

For your convenience, we've added classes that are mapping the current field state and are inherited from the main styles. You can style any of the following states by adding a selector to the css object:

• & .invalid - applied when the field has invalid value.

• & .valid - applied when the field has a valid value.

• & .empty - applied when the field doesn't have any value.

• & .dirty - applied once the user changed the value in the watched field.

• & .touched - indicates that the field has been touched, applied after the first blur event.

Example:

form.field('#my-text-field-id', {
  type: 'text',
  name: 'my-text-field',
  placeholder: 'placeholder text',
  validations: ['required'],
  css: {
    'color': '#1b1d1f',
    'border': 'solid 1px #1b1d1f',
    'transition': 'border-color .15s ease-in-out',
    'border-radius': '5px',
    'padding': '0 10px',
    'box-sizing': 'border-box',
    '&:focus': {
      'border-color': '#11bef5',
    },
    '&.invalid.touched': {
      'color': 'red',
    },
    '&.valid': {
      'color': 'green',
    },
    '@media (min-width: 420px)': {
      'border-color': 'red',
    },
    '@font-face': {
      'font-family': 'PT Mono',
      'font-style': 'normal',
      'font-weight': '400',
      'font-display': 'swap',
      'src': 'local("PT Mono"), local("PTMono-Regular") url(https://fonts.gstatic.com/s/ptmono/v7/9oRONYoBnWILk-9AnCszM_HxEcn7Hg.woff2) format("woff2")',
      'unicode-range': 'U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116'
    },
    'font-family': '"PT Mono", monospace',
  }
});

Web Fonts support

To perfectly match the font of your form with the font on your site you can choose one of the following options:

• Use Web safe CSS and HTML fonts (such as Arial, Verdana, Courier, etc).

• Set @font-face CSS property. The font can be either loaded from the remote server or a locally-installed font.

Examples:

Generic Web font

{
  'color': '#1b1d1f',
  'font-family': 'Arial, Helvetica, sans-serif',
}

@font-face

base64 encode @font-face

Card brand identification

It will automatically determine the type of the credit card and show the desired icon. If you would like to show a card brand icon or an icon for CVV inside your field, just set showCardIcon: true inside the field initialization method.

Card Brand Icon:

form.field('#cc-number', {
  type: 'card-number',
  name: 'cc-number',
  placeholder: 'Card number',
  validations: ['required', 'validCardNumber'],
  showCardIcon: true,
  }
});

Card CVC/CVV Icon:

form.field('#cc-cvv', {
  type: 'card-security-code',
  name: 'cc-cvv',
  placeholder: 'CVV',
  validations: ['required', 'validCardSecurityCode'],
  showCardIcon: true,
});

You're always able to get cardType value from the form state.

We're supporting the following card brands:

Card Brand	State cardType	Card Icon	CVV Icon
Visa	visa
Visa Electron	visaelectron
Maestro	maestro
Mastercard	mastercard
Amex	amex
Discover	discover
Dankort	dankort
Diners Club	dinersclub
JCB	jcb
UnionPay	unionpay
Forbrugsforeningen	forbrugsforeningen
Elo	elo
Hipercard	hipercard

By default, the icon is a 31px-width image positioned on the right side of the input, but you can overwrite these styles as shown in the examples below:

Show Card Icon

form.field('#cc-number', {
  type: 'card-number',
  name: 'cc-number',
  placeholder: 'Card number',
  validations: ['required', 'validCardNumber'],
  showCardIcon: true,
  css: {
    color: '#1b1d1f',
    border: 'solid 1px #1b1d1f',
    transition: 'border-color .15s ease-in-out',
    borderRadius: '5px',
    padding: '0 10px',
    boxSizing: 'border-box',
    '&:focus': {
      borderColor: '#11bef5',
    },
  }
});c

pattern	RegExp. Custom card validation pattern	required
format	RegExp. Mask for the input (e.g. split value with spaces)	/(\d{1,4})/g
length	Array. Card number length	[16]
cvcLength	Array. Available CVC number length	[3,4]
luhn	Boolean. Specify whether card should pass luhn check or not	true
useExtendedBin	Boolean. Return 8 digit BIN in the form state.	false

Add new card brand

form.field('#cc-number', {
  type: 'card-number',
  name: 'cc-number',
  placeholder: 'Card number',
  validations: ['required', 'validCardNumber'],
  showCardIcon: true,
  addCardBrands: [{
    type: 'mycard',
    pattern: /^221/,
    format: /(\\d{1,4})/g,
    length: [16, 19],
    cvcLength: [3, 4],
    luhn: false,
  },],
});

Override default icons

You can customize VGS Collect.js icons, but due to security reasons, regular HTTP(s) URLs are not allowed. You can pass a Data URL with an image encoded.

Example:
