Simple test page

Let's say you have a textarea at the bottom of the page. (you have a textarea at the bottom of the page)

If you drag the textarea so it is bigger, and then make it smaller, it will shrink on every mouse move, basically. It will shrink too fast.

So if there was another way the textarea was resized, it wouldn't do that.

I propose a new method of resizing it, written in Pseudocode.

When you start to resize the textarea:
    set start_x = mouse coordinates on the screen(x)
    set start_y = mouse coordinates on the screen(y)
    set start_width = width of textarea()
    set start_height = height of textarea()

When you drag the mouse on the screen:
    set move_x = mouse coordinates on the screen(x)
    set move_y = mouse coordinates on the screen(y)

    set diff_x = move_x - start_x
    set diff_y = move_y - start_y

    set_width_of_textarea ( start_width + diff_x );
    set_height_of_textarea( start_height + diff_y );


I hope there is no mistake in my pseudocode but that is basically my idea. I may need to clarify a few points.

Drawbacks:
  There is the possibility that the mouse cursor position is not syncronized with the resize handle of the textarea.

Advantages:
  The resizing of the textarea is relative to the screen and not the page
