ReCaptcha API v2 Styling

Question

I have not had much success finding how to style Google\'s new recaptcha (v2). The eventual goal is to make it responsive, but I am having difficulty applying styling for ev

Answer 1

Late to the party, but maybe my solution will help somebody.

I haven't found any solution that works on a responsive website when the viewport changes or the layout is fluid.

So I've created a jQuery script for django-cms that is dynamically adapting to a changing viewport. I'm going to update this response as soon as I have the need for a modern variant of it that is more modular and has no jQuery dependency.

html

css

.g-recaptcha { display: none; }

.g-recaptcha.g-recaptcha-initted { 
    display: block; 
    overflow: hidden; 
}

.g-recaptcha.g-recaptcha-initted > * {
    transform-origin: top left;
}

js

window.djangoReCaptcha = {
    list: [],
    setup: function() {
        $('.g-recaptcha').each(function() {
            var $container = $(this);
            var config = $container.data();

            djangoReCaptcha.init($container, config);
        });

        $(window).on('resize orientationchange', function() {
            $(djangoReCaptcha.list).each(function(idx, el) {
                djangoReCaptcha.resize.apply(null, el);
            });
        });
    },
    resize: function($container, captchaSize) {
        scaleFactor = ($container.width() / captchaSize.w);
        $container.find('> *').css({
            transform: 'scale(' + scaleFactor + ')',
            height: (captchaSize.h * scaleFactor) + 'px'
        });
    },
    init: function($container, config) {
        grecaptcha.render($container.get(0), config);

        var captchaSize, scaleFactor;
        var $iframe = $container.find('iframe').eq(0);

        $iframe.on('load', function() {
            $container.addClass('g-recaptcha-initted');
            captchaSize = captchaSize || { w: $iframe.width() - 2, h: $iframe.height() };
            djangoReCaptcha.resize($container, captchaSize);
            djangoReCaptcha.list.push([$container, captchaSize]);
        });
    },
    lateInit: function(config) {
        var $container = $('.g-recaptcha.g-recaptcha-late').eq(0).removeClass('.g-recaptcha-late');
        djangoReCaptcha.init($container, config);
    }
};

window.djangoReCaptchaSetup = window.djangoReCaptcha.setup;
