Question

我正在一个网站上工作并且大部分都按照我想要的方式进行了规划，但我遇到了Internet Explorer 9（IE9）的一些格式问题。我已经通过论坛阅读了很多元素的定位，并且z-index和我如何解决我的问题。如果我在Chrome，Firefox，IE11中测试我的网站，一切看起来都不错。

然而，在IE9中（不确定大约10个）我的Overlay div隐藏在图像后面。我遇到问题的网站可以在http://ktwu.trilionstudios.com/wp-content/themes/ktwu/csstest.html找到我正在使用静态页面进行测试，但最终会将其移动到常规模板和动态生成的内容中。

您似乎没有为 #homevideo .overlay 类添加z-index。

尝试：

#homevideo .overlay {
position: absolute;
background-color: rgb(0, 0, 0);
background-color: rgba(0, 0, 0, 0.83);
bottom: 5%;
left: 0px;
padding: 0% 0%;
width: 100%;
z-index: 100;
}

您还应该在页面顶部添加doctype声明。我建议使用以下内容：

<!DOCTYPE html>
  <html>
    <head>
      ...
