Fix canvas warping

Question

为什么画布在调整大小时会拉伸内容，我该如何处理呢？

Answer 1

Can you specify? What kind of canvas? For what I understand, I assume you are looking for manipulating the resize property of an element.

You can change this by specifying the object's resize propery:

<textarea style="resize: none;">
</textarea>

Unfortunately, this is a CSS3 property so only Mozilla and Webkit can support the resize property. You can check this out in http://www.w3schools.com/cssref/css3_pr_resize.asp

Allowed resize: none | both | horizontal | vertical
