Styling as a static ui element, not a dropdown

[rdickert]

I find that when I render <LoginButtons visible /> and am using it as a static component rather than a dropdown, I also want this css:

#login-dropdown-list {
  position: relative;
}

which makes it behave as a block instead of being on top of other content. I don't know if it makes sense to add that in the component somehow, or just maybe add something in the readme so people can use this without having to figure it out.

I also found that it overlapped with the component above, so I ended up using

#login-buttons {
  margin-top: 10px;
}

but not sure if that's specific to the app I was working with.
