The solution here works for changing the height dynamically.

http://jsfiddle.net/FNMSP/2/

1.  I need it to auto-shorten the height of the textarea when text is erased (the reverse of what is doing now )

2. I also need that the width of the textarea resizes automatically (shorten or  lenghten)
So it will enlarge till reaching a max-width, then will start increasing the height.

Thank you!

Since you are using MooTools

For the width - that would be an unusual one since the textarea would automatically wrap so there is no defined width to calculate.
