Displays an image overlay effect on hover.

- Use the `:before` and `:after` pseudo-elements for the top and bottom bars of the overlay respectively. Set their `opacity`, `transform` and `transition` to produce the desired effect.
- Use the `<figcaption>` for the text of the overlay. Set `display: flex`, `flex-direction: column` and `justify-content: center` to center the text into the image.
- Use the `:hover` pseudo-selector to update the `opacity` and `transform` of all the elements and display the overlay.

  </figcaption>
</figure>
