Implement (i) icon for each hover

[TimDaub]

Scope

• Initially I ask asking over on the classless repo if they had a way to add an "information" icon for a mobile-friendly hover option: Add info icon modal emareg/classlesscss#11
• Turns out they have this already implemented:

Deliverable

• For each hover element on the front page, implement the (i) icon

Time estimate

• 1h

I tried it out and I think the symbol is outdated , you need to come up with an alternative icon
