Hello. I am creating a website that is using layers with dividers at the top and the bottom. Layers are NOT nested. One layer will be flush against another going from top to bottom, each as a container for some text and images. Each layer has a divider at the top and the bottom. In Chrome, the page looks perfect no matter which breakpoint I view the page at. In Firefox, there are spaces between most of the layers/dividers depending on which breakpoint I view it at. Here are a few screen shots to show what I am seeing:
Chrome:
Firefox:
Just tested and it's showing the gaps in both IE11 and MS Edge, too. So, only Chrome is displaying the page correctly (or as it is shown in Web Builder's view).
EDIT:
It actually looks like the divider is up a pixel or two from the bottom of the layer's edge. I can see a thin strip of the layer's background image showing between the bottom divider and the top of the next layer. So, the bottom divider does not appear to be flush at all times. The top dividers appear fine (from what I've seen).
