【问题描述】：
目前我正在使用名为EZPZ tooltips 的javascript 工具提示。这是 EZPZ 工具提示的demo 页面。
我有这种带有 html 和 css 的布局。
最大的 div 与 margin-left:auto 相对位置；和边距右：自动；并且在小盒子里面是绝对位置。
这是这个 html 页面的完整代码。

当我悬停时，小灰色框，工具提示显示为这样，这是错误的。
但如果我删除 margin-left: auto;和边距右：自动；从包装类。有用。这是工具提示应该显示的实际外观。
我认为它在某个地方发生了冲突。但我不知道如何解决它。无论如何要使 div 居中而不使用 margin-left:auto;和边距右：自动； ?我尝试使用 margin:0px auto;和 text-align:center 也是。但是工具提示仍然出现同样的问题。
我需要网站处于中心位置，并且工具提示也需要在悬停内容下正常工作。请帮助我。谢谢。
