How can i place a relative button at a fixed place right of the brwowser window?

[rania15]

I have a relative positioned button with a fixed left value on my page which keeps its location when scrolling. The only problem i got is when the browser window width gets changed or when the client device has a small screen. In this case the button is outside the visible screen.I think it would be nice to define that this button should always be 50px from the browser window right limit. How can i achieve this?Update: I used \[code\]float: right\[/code\] already, which is almost what i want, but the button is still to close to the browser window border (is over the vertical scollbar). To place it 50px moreto the left would solve this issue.
