HTML无法响应更大的屏幕分辨率

Question

我正在为一个客户工作一个网站，而且真的很奇怪。您可以在此处找到当前网站http://107.170.219.136

网站外观和工作查找我的屏幕分辨率（1920x1080），但似乎对于较大的分辨率，横幅和横幅文本不响应屏幕大小。当我在2560x1440的屏幕分辨率上测试网站时，它显示如下：

2560x1440

虽然，测试人员使用与I相同的屏幕分辨率报告相同的问题。我一直在寻找可能的解决方案，例如向我的CSS添加媒体断点并将横幅设置为max-wdith: 100%;，但没有。这是该网站的标题HTML部分：

问题在于您网页上的img { max-width: 100%; } CSS。这将只允许图像长到100％的最大宽度，然后不会进一步扩展。这对于您网站上的图片来说是一个很好的规则，但如果您希望图片超出超宽屏幕的原始宽度，那就太棒了。如果您添加此CSS，该图片应缩放到更大的屏幕#banner > img { width: 100%; }
