Why They will never look lined up:

  • the background shows its height to be different. Width the same.

They are too similar for a great Masonry effect.

Works with Grid Strips as it appears to use the CSS Contain effect. Which I could recreate a similar look with Grid Simple 1:1, but then, there’s no point. 4:3 is close, but then it was without the white background added to make them all the same. the image is not.
