10 Common Web Layouts Explained Using CSS Grid and Flexbox

A DEV Community guide breaks down 10 frequently used web layouts and explains when to choose CSS Grid versus Flexbox for each. The core distinction is straightforward: Flexbox handles single-direction arrangements such as rows or columns, while Grid manages two-dimensional layouts involving both rows and columns simultaneously. Layouts covered include sidebar-and-content dashboards, split screens, bento grids, F-shaped page structures, and alternating Z-pattern landing page sections. For each pattern, the guide provides minimal, reusable CSS snippets alongside the reasoning behind the tool choice. The article emphasizes understanding layout logic over memorizing code patterns, aiming to help developers make deliberate design decisions.
