Masonry Layout

Creates a masonry-style layout that is especially useful when working with images.

• Create a masonry-style layout that consists of "bricks" that fall into each other with either a fixed width (vertical layout) or a fixed height (horizontal layout), forming a perfect fit. Especially useful when working with images.
• Define .masonry-container This is the container for the masonry layout and .masonry-columns, an inner container in which .masonry-brick elements will be placed.
• Apply display: block to .masonry-brick elements to allow the layout to flow properly.
• Use the :first-child pseudo-element selector to apply a different margin for the first element to account for its positioning.
• Use CSS variables and media queries for greater flexibility and responsiveness.
