不透明度在 IE 中不起作用？

Question

在我的演示页面上 - (click here) 当它在 IE 11 中显示时，（下面的这个 HTML 标签应该是不可见的，它至少适用于其他浏览器，例如 FF，Chrome, Yandex) 但不知何故它显示在左侧。我尝试了很多，但找不到任何解决方法来解决这种情况。

<a href="#" class="close"></a>

这是我的样本HTML:

<!doctype html>
<!--[if IE 6 ]><html lang="en-us" class="ie6"> <![endif]-->
<!--[if IE 7 ]><html lang="en-us" class="ie7"> <![endif]-->
<!--[if IE 8 ]><html lang="en-us" class="ie8"> <![endif]-->

请帮忙！

Answer 1

您的容器正在设置其中所有内容的不透明度。所以你的 .container 应该是相对的，所以尝试将 position 添加到 relative 并查看它的行为。

#about .container, #subscribe .content, #contact .container {
    opacity: 0;
    position: relative;
}

Answer 2

如果您将应用不透明度：0 的元素设置为位置：相对可能会解决问题。

我想，IE 11 的工作方式有些不同。您的关闭元素设置为位置：绝对。但它与设置为 opacity: 0 的元素无关，而是与该元素的父元素有关。

不透明度在 IE 中不起作用？
