Autosize

When nothing is entered inside a textarea, nobody will notice the Autosize is loaded on a page.

But when large blocks of text are entered inside a textarea, the plugin slowly adds new lines to the input section, so the user can fit and view all his content all at once.

The plugin includes support for all major browsers, can be expanded with smooth CSS 3 transition effects, and can also trigger callback functions when the textarea is expanded.

A small demo is included with the Autosize download package.
