HTML-CSS : Exercise-37 with Solution

Using HTML, CSS displays a menu overlay when the user hovers over the image.

Use a <figure> to wrap the <img> element and a <div> element that will contain the menu links.
Use the opacity and right attributes to animate the image on hover, creating a sliding effect.
Set the left attribute of the <div> to the negative of the element's width. Reset it to 0 when hovering over the parent element to slide in the menu.
Use display: flex, flex-direction: column and justify-content: center on the <div> to vertically center the menu items.
