How do I create a static or fixed img menu tab? I've created the thing to stay where I want it to be, but when scaling smaller or bigger the browser, the tabs move.

I HAVE this to show as an example. When I open the page it opens up the way it's supposed to, but when scaling it look horrible.
#home{
position:fixed;
right:40px;
top:20px;
}

I hope what I'm saying makes sense.
