Spacing question

[matelot20]

I’ve trying to understand spacing with CSS and have been using background-color to see where each layout fits on the screen. I notice that the bottom bar and lower sections always have spaces between the 2 areas. No matter what I use margin, padding or border=0px to close the gap, it doesn’t do anything. Is it normal that there must be spacing between each section? What code should I use to close the gap between bottom_bar and bottom_left/right. Thanks.

@matelot20 what you see is most probably the margin of the modules
Try changing that

.bottom_bar .module {
  margin: 0;
}
