Width with percent

Module is working (after debugging the two things I have found in the code) but there are some things you might validate.
This module is not made with the coding standards of Drupal.
If you check the module with coder module you will see it.

After this quiet tecnical things there is one inquiery:
Normaly you are used to manage height and width outside the content because it is pure design. I think if width is 100% all time and height will be managed in the field settings (like all you are used to have in the widget form less the WikiLoc ID) this is a quiet nice module.
