Hi,
I'm using WP 3.9.2 and Atahualpa 3.7.11

I'm trying to add a background image to the home page of my site by adding the following code to the html/css inserts :

body.home {background-image: url(wp-content/themes/atahualpaAJT/images/bck3.jpg);
background-position: center;
background-repeat: no-repeat;
background-attachment: fixed;
width:100%;
}

Problem is that the post container seems to be covering my background and pushing it downwards. You can admire the disaster here :

Could you please tell me what I'm doig wrong ?

Thanx in advance

Why are you still on an old Atahualps release?
Why are you still on an old WP release?

you are not doing anything wrong, the post formatting has a background-color of #000000 (black) and that sits on top of the body background.

Duh...
I guess when you look too hard at somtehing it's easy to miss the obvious.

Thank you very much for your help.

And you're right, I'll proceed to the updates ASAP.
