Background color of middle of Content page

I tried the following code (from another thread) in the Syling section. But the color is still white. I would like to make it the same as the background on the outer left and right of the screen.

ie the background color of all the text under Sample page, etc. should not be white

Here's the code I used:
body{
background-color:#F1F1F1!important;
}
.bgimagecolor {
background-color:#F1F1F1!important;
}

 

I fixed it...

I used this code instead. (to also remove border)
.content-main.fullwidth {
background-color: #f5f5f5;border: none!important;
}
.content-info {
border: none!important;
}
