Slotted Corners Photo Album Effect in CSS

The code creates an effect where the photographs appear as if they are slotted into an album page.

The shadows and cut-out corners simulated by the CSS give the impression that two corners of each photo are inserted into slits on the page, similar to a traditional photo album. This visual trick is achieved through specific CSS properties that manipulate the shadows and shapes to give depth and realism to the paper-like background and photo presentation.
