I’m Eric 🙂 ….or did you mean to reply to a different thread that @Wes was on?
There isn’t any extra margin at the bottom of your text other than what comes with paragraph tags. The bottom margin that is coded for p tags affects everywhere throughout your entire site. I’d leave that as it is unless you really need to reduce more space.
p {
margin: 0 0 30px;
padding: 0;
}
You are talking about the space underneath the button right? If you are, then that space is your p tag above which is usually found after the body code at the top of the style.css
