Moving BBPress Favorite and Subscribe links to the center

On this page:
There is a favorite link and there is a subscribe link, I would like them to be moved to the center.

I also have a CSS question to throw in here real quick. When ever I try to move the links over, I will write something like

#bbpress-forums div.bbp-topic-content a, #bbpress-forums div.bbp-reply-content a {
margin-right: 100px;

One link seems to come over like normal, but the other link stays in the same spot or spaces itself out. See second screenshot. Why is this happening? Is there something I am doing wrong? I cannot figure it out, when trying to provide coding changes for peoples menus, the same thing happens.

Thanks for your help.
