I tweaked the styles a bit so the page doesn't look that broken. Related issue: #5
Removed horizontal scrollbars
Simplified the containers with flex, added boxshadows
Separated the listed items by variating the bg-color of odd elements
Fixed the popup so the header is not see-through, added boxshadow for the popup so it doesn't mix with the rest of the page that much and added an animation to the close button. (TODO: Add dark overlay to the background, so the focus stays on the popup)
