Suggestions for Flood (and Earthquake) Realtime filters

[lucernae]

Taken from @ivanbusthomi 's suggestions:

So here's my suggestion on reducing whitespace in the Filters area.

• I think we can also make the warning text Value must be greater than or equal to 0. smaller, or just responsively resize the Filters box if the warning appear.
• It would be great if the margin of Filters and Flood section are same.
• The accept and clear button should be aligned with the other input maybe
• Maybe also add Clear and Accept text on top of the button?
