As simple as it sounds to get you were you want, the harder it is actually to fix your problem because you didn’t write the code yourself. There’s not even a background-image inside the "div" or "a" tag.
A good advice: throw that editor (whatever software that is) away (seriously) and LEARN CSS by hand-coding it – it is the only right way to do it. Everything else won’t get you far and you will waste a lot of time trying to understand machine-coded CSS which will never be as simple and flexible as it needs to be.
To illustrate how simple your problem is, here’s some code
background: url(someimage.jpg) top left no-repeat;
background-position: bottom left;
There are newer books but this is the only CSS book I read and which I can still recommend for beginners.
