覆盖google recaptcha css以使其响应

Question

我在一个网站(不是Wordpress网站或Joomla)中安装了Google Recaptcha所以不要提供任何WP插件或Joomla扩展:)

我的问题是,该网站是响应式的,而recaptcha则不是.当我使用Firebug查找其样式时,我意识到不仅Google提供的库不包含css文件,而且我无法在custom-styles.css文件中覆盖它们,因为Google非常周到地应用了!important选择器hack在他们的CSS中一切,但我甚至尝试对它进行分类,以便我可以做出违规并希望覆盖Google的样式但是插件不起作用:(

有任何想法吗？

ps我也没有使用不同的重新验证码.抱歉.我敢肯定这里有一些收藏极客;)

这是HTML.这就是recaptcha.php从服务器呈现的内容.这不是我在实际PHP页面中所拥有的...(没有CSS,这是主要问题)

<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">

这就是我在页面中所拥有的

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

这是我的问题

更改了自动高度和媒体查询

@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;
    }

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

}

对于reCAPTCHA（需要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(); });

});

这基本上检查了您的浏览器宽度，并且还取决于它应该转换的比例。此时的最佳解决方案。
