Widgets and Sidebars

ok…so i’m pulling my hair out. I have my sidebars all setup…well mostly setup using widgets. However between every widget, there is a line, and i’ve been looking over all of the code, and can’t find this line anywhere. I think i’m going crazy, and i’m sure it’s something simple that i’m just overlooking. Does anyone have a quick fix…I just want to remove the lines from my sidebar widgets, or just sidebars for that matter, completly. Thanks.
