Trigger :hover event on mobile

[humitos]

Triggering the :hover event on Mobile is not well supported and it's not recommended. So, in case we want to support this we need to find a different approach.

One idea that I got from Twitter was to detect that the reader is on mobile and if so, add a small icon that when you click it, it triggers the event and shows the tooltip.

I'm not sure if it worth the implementation effort since mobile is not widely used to read documentation but also because the tooltip will be too small probably and hard to read its content. Some experimenting could help to make a better decision here.
