css - Wordpress 移动设备 Logo 调整大小

Question

您好，我遇到了一个小的媒体查询问题。我正在使用的网站上的 Logo 在移动设备上不会调整大小。所以我尝试添加下面的代码，但它什么也没做。有没有办法设置它以便它也可以在移动设备上工作？

只是通过你的网站链接，我发现你的这个 css 没有调用

http://eyeandretina.com.au/wp-content/themes/medicenter/style/responsive.css?ver=4.1

此 css 将覆盖您当前的 css。

尝试在这个 responsive.css 中完成所有代码，或者优先考虑 style.css
