Make image cover screen without scrolling or white space

[anon19893928]

Hi there.

I am trying to make an image z-index: -1 as well as cover the screen without white space or needing to scroll.

I know how to do it with css like below but I have no idea how to do it in bubble.

.img-responsive { background-size: 100%; }

or

.img-responsive { background-size: cover; }

with overflow hidden.

I think you will need to use HTML and CSS plugin to achieve this. But might be other ways I am not aware of.
And please share screenshots or something that describes the issue well. I hope someone will help.
