Horizontal Login code

Hi,

I want to add an horizontal login form in my website with this exact format:

User (Box) Password (Box) Log In (Buttom)
Remember Me (check box) Register (link) Lost Password (link)

I am using the Register Plus Redux but I guess that doesn’t matter?

I’ve tried adding some code I’ve found online at my post-loop.php. However, the result is not horizontal and it’s bigger than the bar, where I would like it to be.

I know I might be asking a lot. But if someone can guide me a little bit it would be awesome.

Thank you in advance
