Are two site templates, the desktop (Which is already ok) and mobile.
In mobile, I want it to display a black background with JUST an image occupying the center of the screen. The entire length (height and width) of the screen has to be just this content. After I press a button, the page scrolls down and the content is displayed.
This is an example I made in Fiddle: http://jsfiddle.net/gtw7375/yrmbsfhu/
But, I don’t know how I can center the image and leave it as the only content occupying the entire height/height of the page.
How to do this?
