Responsive image mosaic

CSS, Layout

Creates a responsive image mosaic.

  • Use display: grid to create an appropriate responsive grid layout.
  • Use grid-row: span 2 / auto and grid-column: span 2 / auto to create items that span two rows or two columns respectively.
  • Wrap the previous styles into a media query to avoid applying on small screen sizes.
