Common Mistakes to Avoid

Not preventing breaks inside cards or images

Add break-inside: avoid to child elements that should not be split across columns (cards, figures, blockquotes). Without this, elements may be awkwardly split.

Using columns for layout instead of content flow

CSS columns are designed for text reflow, not page layout. For component grids, use CSS Grid or Flexbox instead. Columns cannot reorder or span items.
