 - Masonry is not the same as a CSS grid or Flexbox — they usually have both fixed width and height, a Masonry-layout has one variable dimension (width or height), and forms a perfect fit.
 - `.masonry-container` is the container for the Masonry layout. Within that container, there's a div `.masonry-columns`, which will automatically put each child element `.masonry-brick` into a Masonry layout. There's some CSS that ensures that `.masonry-brick` is a block-level element and that the first one will have no margin on top.
 - You can change the CSS3 variables to fine-tune it.
+- Older browsers might need vendor prefixes.
