CSS overflow

overflow hidden:

Hey! I am a "overflow:hidden" text box.
Over the river, and through the wood,
To Grandfather's house we go;
the horse knows the way to carry the sleigh
through the white and drifted snow.

overflow auto:

Hey! I am a "overflow:auto" text box.
Over the river, and through the wood,
To Grandfather's house we go;
the horse knows the way to carry the sleigh
through the white and drifted snow.
