我有一个嵌入在 html 页面上的 SWF 对象。我只是想在屏幕上居中的对象。我已经尝试了一百种不同的方法（将对象的对齐属性设置为居中，将对象包装在 div 中并将其居中……）但对象总是与屏幕左侧齐平。我确信它是一个非常简单的代码行，可以使这项工作，请告诉我那是什么......

PS 这是我尝试编辑使用 SWF 生成的 html 文件时遇到的问题。当我尝试创建一个新的 HTML 文件并将 swf 嵌入其中时，我可以将文件居中，但我无法让它缩放以适应屏幕的垂直尺寸（页面底部的对象在下面的视图中，而在自动生成的 html 文件中，swf 自动缩放以适应屏幕，但我无法将其居中..) 将不胜感激这些问题的解决方案

这是jsFidle中的一个示例

这很简单，您使用absoluteposition 并指定 50% fromtop然后leftputtop和left负边距一半的容器。

这是CSS：

.container{
    width: 400px;
    height: 400px;
    position: absolute;
    top: 50%;
    left: 50%;
    margin-left: -200px;
    margin-top: -200px;
    background-color: blue;
}

请记住，要使其正常工作，您需要固定大小或 javascript 更新窗口调整大小事件的边距！

这是一个 HTML 标记：

<div class="container">
    <iframe width="400" height="400" src="http://www.youtube.com/embed/Awlp8B5os0k" frameborder="0" allowfullscreen></iframe>
</div>
