Styling the iFrame

The iFrame is styled by passing the CSS in the configuration object used to generate the iFrame. The styles object consists of three elements: base, focus and error.

Parameter	Type	Description
base	string	The base style applied to the input element within the iFrame
focus	string	Optional style applied when input element within the iFrame gains focus
error	string	Style applied to the input element if a validation failure occurs
placeholder	string	Allows for the styling of the input placeholder text

var styles = {
    base: "font-family: Arial, sans-serif;padding: 0 8px;border: 1px solid rgba(0, 0, 0, 0.2);margin: 0;width: 100%;font-size: 13px;line-height: 30px;height: 32px;box-sizing: border-box;-moz-box-sizing: border-box;",
    focus: "box-shadow: 0 0 6px 0 rgba(0, 132, 255, 0.5);border: 1px solid rgba(0, 132, 255, 0.5);outline: 0;",
    error: "box-shadow: 0 0 6px 0 rgba(224, 57, 57, 0.5);border: 1px solid rgba(224, 57, 57, 0.5);"
}

In general, you should provide a class for the input, as well as an error class, which the iFrame will automatically append if a validation failure occurs.

Using the configuration depicted in the previous code sample would result in the following CSS applied within the iFrame:

input {
    font-family: Arial, sans-serif;
    padding: 0 8px;
    border: 1px solid rgba(0, 0, 0, 0.2);
    margin: 0;
    width: 100%;
    font-size: 13px;
    line-height: 30px;
    height: 32px;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
}

input.focus {
    box-shadow: 0 0 6px 0 rgba(0, 132, 255, 0.5);
    border: 1px solid rgba(0, 132, 255, 0.5);
    outline: 0;
}

input.error {
    box-shadow: 0 0 6px 0 rgba(224, 57, 57, 0.5);
    border: 1px solid rgba(224, 57, 57, 0.5);
}
