css overflow property syntax
Function:The overflow attribute specifies what happens when the content overflows the element box.
Description: This attribute defines how content that overflows the content area of the element will be handled. If the value is scroll, the user agent provides a scrolling mechanism whether required or not. Therefore, it is possible that scrollbars will appear even if everything fits inside the element box.
Note: All major browsers support the overflow attribute. The attribute value "inherit" is not supported in any version of Internet Explorer (including IE8).

<div>
这个属性定义溢出元素内容区的内容会如何处理。
如果值为 scroll，不论是否需要，用户代理都会提供一种滚动机制。
因此，有可能即使元素框中可以放下所有内容也会出现滚动条。默认值是 visible。
