Bubble Wrapped on "[Plugin: Twitter Widget Pro] Customizing your awesome plugin"

Writing a function for this would be nice, but if I have to, I'll make the changes directly to the Twitter Pro file. I found where this code is located, but I'm unfamiliar with the programming language. It won't let me insert spacing and the divider bars without rendering a white screen on my website.

EDITED TO ADD . . .

Reply, retweet and favorite each have their own CSS class. So I added padding as follows:

.retweet {
    padding: 0 14px 0 14px;
}

But I'm not sure how to add divider bars, unless I add a left and right border, which doesn't look as nice. I'm trying to teach myself the code language, but I'd love some input on this.

Cheerios!!
