30秒学会 CSS 片段 – Menu on image hover

Displays a menu overlay when the image is hovered.

• 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, to create a sliding effect.
• Set the left attribute of the div to the negative of the element’s width and 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.
