What you’re seeing is actually called a “box-shadow” that shows up for the content area of the theme.
You can remove this in your css by looking around line 2196 (unless you’ve added or modified other code in your css)
.entry {
box-shadow: 0 3px 6px rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 3px 6px rgba(0, 0, 0, 0.2);
-webkit-box-shadow: 0 3px 6px rgba(0,0,0, .2);
background: #fff;
margin: 0 3px 40px;
padding: 40px 0 0;
}
Remove the following code from above –
box-shadow: 0 3px 6px rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 3px 6px rgba(0, 0, 0, 0.2);
-webkit-box-shadow: 0 3px 6px rgba(0,0,0, .2);
If you’ve made changes to your css code then it may appear on a different line.
