我在一个学校项目的网站上工作，我正在使用名为quantua的模板。如果您转到模板的实时演示（http://www.templatesjoomla.net/index.php/joomla3-x/244-quantua-joomla-3-x.html），您可以看到，在调整浏览器窗口大小时，图像会缩小，以至于出现黑色背景。我不希望它这样做，如何在此（http://www.websitetemplatesonline.com/free-template/progress-business.html）模板上实现调整大小？我玩css很多，但我失败了，所以我猜它与javascript有关吗？
继承了javascript代码

你在找错了地方。使用firebug来检查并知道正在使用哪个css文件。该文件是default.css。第159行。这就是你应该玩的东西。这就是它的样子
.nivoSlider {
float: left;
position: relative;
width: 100%;
height: 480px;
overflow: hidden;
background: #000
这是影响导航栏显示的代码块。但要消除那里的黑暗，你可以使用这个近距离修复
这并不能保证不会扭曲，尤其是最后一点。但继续努力。
