XF 1.2 Sign-up button misaligned


My forum's sign-up button seems to be misaligned on the portal/home page (XenPorta). I am unsure if it is XenPorta causing this issue, but the button itself is not centered within the loginbutton section only on this portal page. Where should I look or start?

I was also wondering how to separate thread posts into individual boxes (attached image for reference) as opposed to Xenforo's default format.

Thank you!
