This code creates: 1. A red header that's fixed at 200px height 2. A main container that fills the remaining space using `flex: 1` 3. A left sidebar (blue) and right sidebar (green) both fixed at 100px width 4. A middle content area that takes up the remaining space between the sidebars Key features: - Uses `height: 100vh` on body to fill the viewport - Uses nested flex containers (body and main-container) - Uses `flex: 1` to make elements grow to fill available space - No framework dependencies (pure CSS) - Responsive middle section that adjusts to screen width - Fixed size elements where specified (header and sidebars)
