Turning off the resize feature for textareas

Textareas in Drupal are, by default, automatically resizable, thanks to some nifty JavaScript. They can be resized by clicking and dragging the grippie handle right below the element. This, while very handy, can sometimes cause problems when used in tandem with HTML editor scripts which customarily implement their own version of this feature.

In this recipe, we will look to use the Form API to disable the resizable option for a specific textarea—the body field of a typical node form.
