Where can I find the "tooltip" script?

Question

css

We need a script so that when you hover over the picture, a hint appears in it (in the picture). (JS, CSS)
Example:

Preferably not conflicting with Bootstrap (class="thumbnail").

Answer 1

Why is there a hint here? Does anyone know James Hetfield?

Answer 2

Use the Bootstrap tooltip component,
getbootstrap.com/javascript/#tooltips
it has a lot of customization options.
Something like this
jsbin.com/vaqevoqe/1/edit
