The traditional approach to space management between elements in a given web layout often involved using `margin`. This article from discusses the advantages of using CSS's gap property instead for spacing between flexbox and grid items. The gap property provides a cleaner way to manage spacing that works well with wrapped layout items, bidirectional layouts, and across both flexbox and grid layouts. While margins still have their use cases, gap simplifies many common spacing challenges.

Key Points:

  • Gap provides consistent spacing between items even when they wrap to new lines

  • Gap automatically adjusts spacing for right-to-left (RTL) layouts

  • Gap works consistently for both flexbox and grid layouts

  • Gap can be combined with margins/padding when needed

  • Gap has good but not complete browser support, with a way to detect support for flexbox

  • Margins still have uses, but gap reduces the need to manage many spacing edge cases
