Wondering about floating footer
Nick says that when the footer ends up floating with the gallery it is acting the way it has been told to. He tells us we can fix it by adding 'clear: both;', however, I want to know what it is about the footer style code that tells it to float with the gallery if in actuality there is no 'float' code in the footer element. This is a snapshot of my css without fixing the footer. https://w.trhou.se/zgyxlvb5dv

It isn't that the footer is floating, it is that the items above it are set to float.
When something gets "floated" it is taken out of the normal layout and the item loses its height so things that around it behave in such a way to run around that item.
When you clear the float, it just tells the specific item, in this case the footer to respect the height of the floated items so it pushes it back down to where it belongs
Here is an excellent description about floats and clears that should help you understand better.
