Answer 2

This can be resolved by adding 'z-index: -1;' to your footer-bottom class.
Learn more about z-indexing here
In the most basic cases, HTML pages can be considered two-dimensional, because text, images, and other elements are arranged on the page without overlapping. In this case, there is a single rendering flow, and all elements are aware of the space taken by others. The z-index attribute lets you adjust the order of the layering of objects when rendering content.
In addition to their horizontal and vertical positions, boxes lie along a "z-axis" and are formatted one on top of the other. Z-axis positions are particularly relevant when boxes overlap visually.
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Positioning/Understanding_z_index

Answer 3

You should change the z-order of your elements.
Set z-index of footer less than z-index of the navbar (enough set z-index: -1 for footer)
