我在网站(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扩展程序:)
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
选择器在他们的css中攻击了一切,但我甚至尝试对它进行分类,以便我可以破解并希望覆盖Google的样式但是插件无法正常工作:(
有什么想法吗?
P.S。我也没有使用不同的重新验证码。抱歉。我确定这里有一些重新认识的极客;)
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页面中的内容......(没有CSS,这是主要问题)

您可能想要添加一些CSS样式,但我们选择删除一些不必要的内容。

margin: 0 !important;
width: 100% !important;

对于reCAPTCHA(requiers 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(); });
});
这基本上会检查您的浏览器宽度,并取决于它应该转换的比例。此时的最佳解决方案。

最好的方法是使用google recaptcha并使用此css代码进行响应,
#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;
}

您只需为所需的特定设备添加一些转换样式:
@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; }
}
