Why it worked
The video effectively uses clear, concise on-screen text and visual examples to explain a common web development concept. The breakdown into distinct methods (Grid and Media Queries) with corresponding code snippets makes it easy for viewers to understand and apply the information.
Summary
The video displays three different screen layouts: desktop, tablet, and mobile. It then shows two methods for achieving responsive layouts in CSS: using Grid and using Media Queries, with accompanying code snippets for each.
