我刚才在Chromium上看到过
>如果调整大小,我无法将元素的大小调整到小于初始高度的高度：vertical或resize：both
>如果调整大小,我无法将元素的大小调整为小于初始宽度的宽度：horizontal或resize：both.
演示：http://jsfiddle.net/3rdj4/3
我看过w3c spec,我猜这个问题是由于这个原因：
The user agent may restrict the resizing range to something suitable,
such as between the original formatted size of the element,and large
enough to encompass all the element’s contents.
有没有办法,即使Chrome应用了上面的段落呢？
注意：我使用的是Chromium 30.0.1592.0(216775)
解决方法
我会说不(没有javascript).
Custom CSS to allow chrome textarea resize smaller than initial state?
The fact you cannot resize a textarea under its initial dimensions is reported as a bug (07001)
