Coming soon page

Hello I have came across some difficulties. I wasn't able to center input precisly, even though //text-align: center;// was used on body. My second problem was mobile-phone layout where I have decided to put the image as background but this was quite harsh solution. It would be better to do it by div but I wasnt able to adjust the image to cover full width since it was inside general //div class='container'// which has some padding on sides so the whole page is offset from sides.
