　　CSS3新增了resize属性，该属性允许用户通过拖动的方式来修改元素的尺寸。本来resize应该翻译为缩放，但在实际测试中通过resize属性只可以在宽高基础上实现拉伸效果，而无法实现缩放到小于宽高的效果。

　　[注意]IE浏览器不支持resize属性

resize

　　resize与overflow关系紧密，只有当元素的overflow属性值不是visible时，resize才会起作用

　　[注意]因为文本框本身就具有overflow:auto的属性，所以自带resize属性

　　值: none | both | horizontal | vertical

　　初始值: none

　　应用于: 块级元素、替换元素、表单元格

　　继承性: 无

<span style="color: #000000;">none: 用户无法调整元素尺寸
both: 用户可调整元素的宽度和高度
horizontal: 用户只可调整元素的宽度
vertical: 用户只可调整元素的高度</span>

　　[注意]在win7下resize拖拽区域的大小是17px*17px，实际上它就是滚动条尺寸
