New Paradigm

CSS Grid Layout is the most powerful layout system in the web. If Flexbox was about element " neighborhood " in a row, then Grid is about Space.

Main Differences:

  1. 2D vs 1D: Flexbox controls either a row or a column. Grid controls the entire grid (both simultaneously).
  2. Skeleton vs Content:
    • In Flexbox, elements themselves " push " each other apart.
    • In Grid, you first build the " cell " , then place content inside it.
Tip

Use Grid for entire page layout (Header, Sidebar, Main, Footer), and Flexbox for aligning elements inside these blocks (e.g., icon and text inside a button).
