Format multi-select (or MC) button only for single question

Hi all, I am using a dynamic theme with the classic layout. I use CSS to format the color and hover characteristics of buttons for MC and multi-select "buttons" / boxes. Is there a way to override these settings for a single question? What I am trying to achieve is the following (maybe someone has a better idea for it): - I have a traditional MC questions - Underneath it (or even to the right of it), I am trying to create a button or link that would allow me to display a text entry question underneath with in-page display logic. (Basically, after each MC question, respondents should have the option to open up a comment box.) - If I use a traditional MC or MS question for it, it looks very inelegant because the "button" I create is large and colored. I am hoping to style it very minimally (e.g., white on white with no border, and blue underlined text) Any help is appreciated! Thanks, G2000
