How I built currency conversion tooltips 4 years ago
I often have an unreliable internet connection on the U-Bahn, in hotels, in developing countries, and in Brandenburg

It'd be nice to add a `tabindex` value and add a `:focus` part to the tooltip CSS to make it appear for users navigating via their keyboard rather than mouse. If you look up 'accessible tooltips' there might be a few other tips.
