## Description
< section id = 'description' >
The buildings are stacked on top of each other and running off the screen. Let's fix that. Add the properties `display: flex;` , `align-items: flex-end;` , and `justify-content: space-evenly;` to the `background-buildings` class. This will use Flexbox again to evenly space the buildings across the bottom of the element.
