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。
我使用html和CSS进行这种布局。
最大div的位置相对于margin-left：auto;和margin-right：auto;小盒子里面的位置是绝对的
这是此html页面的完整代码。

当我将鼠标悬停在灰色的小方框上时，工具提示将显示为错误的。
但是如果我删除margin-left：auto;和margin-right：auto;从包装类。有用。这是工具提示应显示的实际外观。
我认为这是发生冲突的地方。但是我不知道如何解决它。无论如何没有使用margin-left：auto将div居中？和margin-right：auto; ？我尝试使用margin：0px auto;和text-align：center也。但是工具提示仍然发生相同的问题。
我需要该站点位于中心，并且工具提示也必须在悬停内容下才能正常工作。请帮助我。谢谢。
最佳答案
从外观上看，keepInWindow()是您的敌人。

好。我一直为jQuery的醉汉插件发誓。这是最好的工具提示插件，它的编码非常好。看这个：http://jsfiddle.net/gyLpJ/1/
