Overriding google recaptcha css to make it responsive

I installed Google Recaptcha in a site (not a Wordpress site or Joomla) So do not offer any WP plugins or Joomla Extension :)

My problem is, the site is responsive and recaptcha is not. When I use Firebug to find its styles I realized that not only the library that Google provides does not contain the css files, and I can't override them in my custom-styles.css file because Google, very thoughtfully, applied the !important selector hack to EVERYTHING in their css, but I even tried classing it so that I can make a breach and hopefully override Google's styles but then the plugin doesn't work:(

Any ideas?

p.s. I am not using a different re-captcha either. Sorry. I'm sure there are some recaptcha geeks out here ;)

Here is the HTML. This is what the recaptcha.php renders from the server. THIS IS NOT WHAT i I HAVE IN THE ACTUAL PHP PAGE...(Don't have a CSS, and that is the main problem)

<div id="recaptcha_widget_div" style="" class=" recaptcha_nothad_incorrect_sol recaptcha_isnot_showing_audio"><div id="recaptcha_area"><table id="recaptcha_table" class="recaptchatable recaptcha_theme_red">

This is what I do have in the page

  require_once('recaptchalib.php');
  $publickey = "your_public_key"; // you got this from the signup page
  echo recaptcha_get_html($publickey);

And here is my problem

For reCAPTCHA (requires jQuery):

$(function(){
  function rescaleCaptcha(){
    var width = $('.g-recaptcha').parent().width();
    var scale;
    if (width < 302) {
      scale = width / 302;
    } else{
      scale = 1.0; 
    }

    $('.g-recaptcha').css('transform', 'scale(' + scale + ')');
    $('.g-recaptcha').css('-webkit-transform', 'scale(' + scale + ')');
    $('.g-recaptcha').css('transform-origin', '0 0');
    $('.g-recaptcha').css('-webkit-transform-origin', '0 0');
  }

  rescaleCaptcha();
  $( window ).resize(function() { rescaleCaptcha(); });

});

This basically checks your browser width and depends the scale it should be transformed too. Best solution around at this point.

Simple you have to copy style attribute from below code to your code then your problem will solved.

<div class="g-recaptcha" data-theme="light" data-sitekey="XXXXXXXXXXXXX" 
style="transform:scale(0.77);-webkit-transform:scale(0.77);transform-origin:0 0;- 
webkit-transform-origin:0 0;"></div>

In my case I decreased the scale of it and I force some horizontal alignment on center through Bootstrap 4 grid system. Click here to see the result.

Code:

<div class="row justify-content-center">
     <div class="col g-recaptcha" data-sitekey="check_reCaptcha_doc_to_set_this" style="width: 304px !important; max-width: 304px !important; -ms-transform: scale(0.8, 0.8); -webkit-transform: scale(0.8, 0.8); transform: scale(0.8, 0.8); margin: 0px; padding: 0px;">
     </div>
</div>

This is my solution with media queries. I use scale to scale it down to a reasonable size for mobile.

A simple and effective solution:

@media (max-width:575px) {
    #rc-imageselect, .g-recaptcha {
        transform:scale(0.77);
        transform-origin:0 0;
        margin-bottom: -20px;
    }
}

You can simply add some transform style for the specific device you needed:

 @media only screen and (max-width : 767px)     {

 #rc-imageselect, .g-recaptcha {
    transform: scale(0.77);
    -webkit-transform: scale(0.77);
    transform-origin: 0 0;
    -webkit-transform-origin: 0 0; }
}

The best way is that you use the google recaptcha and use this css code to make responsive,

#rc-imageselect, .g-recaptcha {
   display: inline; //the most important
}

#rc-imageselect{
   max-width: 100%;
}

.g-recaptcha>div>div{
   width: 100% !important;
   height: 78px;
   transform:scale(0.77); //the code to rescale the captcha obtained in this page
   webkit-transform:scale(0.77);
   text-align: center;
   position: relative;
}

Google has complete documentation on how to style recaptcha forms here:

https://developers.google.com/recaptcha/docs/display

and you can completely override the html/css they provide with your own.

Changed auto height and media query

@media only screen and (max-width : 480px) {
    #recaptcha_challenge_image{
    margin: 0 !important;
    width: 100% !important;
	height: auto !important;
    }
    #recaptcha_response_field
    {
    margin: 0 !important;
    width: 100% !important;
	height: auto !important;
    }
    .recaptchatable #recaptcha_image {
    margin: 0 !important;
    width: 100% !important;
	height: auto !important;
    }
    .recaptchatable .recaptcha_r1_c1, 
    .recaptchatable .recaptcha_r3_c1, 
    .recaptchatable .recaptcha_r3_c2, 
    .recaptchatable .recaptcha_r7_c1, 
    .recaptchatable .recaptcha_r8_c1, 
    .recaptchatable .recaptcha_r3_c3, 
    .recaptchatable .recaptcha_r2_c1, 
    .recaptchatable .recaptcha_r4_c1, 
    .recaptchatable .recaptcha_r4_c2, 
    .recaptchatable .recaptcha_r4_c4, 
    .recaptchatable .recaptcha_image_cell {

    margin: 0 !important;
    width: 100% !important;
    background: none !important;
	height: auto !important;
    }

}

You may want to add some CSS styling but we opted for removing everything that wasn't necessary.

Add this code to your css file :

@media (min-width: 320px) and (max-width: 480px) {
		#recaptcha_challenge_image{
		margin: 0 !important;
		width: 100% !important;
		}
		#recaptcha_response_field
		{
		margin: 0 !important;
		width: 100% !important;
		}
		.recaptchatable #recaptcha_image {
		margin: 0 !important;
		width: 100% !important;
		}
		.recaptchatable .recaptcha_r1_c1, 
		.recaptchatable .recaptcha_r3_c1, 
		.recaptchatable .recaptcha_r3_c2, 
		.recaptchatable .recaptcha_r7_c1, 
		.recaptchatable .recaptcha_r8_c1, 
		.recaptchatable .recaptcha_r3_c3, 
		.recaptchatable .recaptcha_r2_c1, 
		.recaptchatable .recaptcha_r4_c1, 
		.recaptchatable .recaptcha_r4_c2, 
		.recaptchatable .recaptcha_r4_c4, 
		.recaptchatable .recaptcha_image_cell {
		
		margin: 0 !important;
		width: 100% !important;
		background: none !important;
		}

	}
