I was searching for a simple Javascript code snippet to live resize text area. After searching a lot, today I have found one simply cool.

I have found this blog: http://www.mollerus.net/tom/blog/2008/02/clickanddrag_resizing_of_a_textarea.html where I got the link of the main script.

The main script is located at http://dev.turnipspatch.com/trac/wiki/TextareaResizer#Example

Just download it and follow the simple example. Sure, you will see that you can resize any or all text area of your web page.
