Fix formatting for top bar of Map to render correctly on all screens

[beegeiger]

The bar at the top of the Map page which includes the year sliders renders correctly on chrome on a computer, but doesn't always depending on the browser or device. Fix the CSS so that it looks good in every context.

You want to say that the year slider doesn't get render properly in every browser or device?
Am i correct? or is it something else?

Exactly, particularly on mobile, the buttons in the bar can appear way too big or small and can even awkwardly stack so they don't fit in the top bar.
