CSS forms change the height on a text field and not effect other text fields

Hi there

Sorry I would like to change the height on the 'comments' field only, any suggestions on what to change in the CSS so it will enlarge the comments text field and not effect the other text fields? Please items attached below. Is it possible to use reference the ID field? (see line 53) If you would like to view the the full url please follow me and I can supply directly.
