The effect of using the height and width attributes of CSS is the same as that defined by rows cols. You can drag the lower right corner The icon changes size. However, excessive dragging will affect the page layout and make the page unsightly. You can disable dragging and fix the size by adding the following style:
<html> <head> </head> <form> <textarea id='memo'style="min-height:50px;min-width:70px;max-height:50px;max-width:70px;">这是PHP中文网的留言框 </textarea> </form> </html>
This code is displayed in the browser as follows:
