CSS Layout Tools: Flexbox, Grid & Responsive Design
CSS layout is the backbone of every web page, but Flexbox and Grid have dozens of properties that interact in complex ways. These visual tools let you experiment with layout properties interactively and see exactly how each change affects the result — far more intuitive than editing CSS and refreshing.
Flexbox and Grid solve different problems. Flexbox is ideal for one-dimensional layouts — a row of buttons, a navigation bar, a card with vertically stacked content. Grid handles two-dimensional layouts — page-level structures with rows and columns, dashboard panels, image galleries. The Flexbox Playground and Grid Generator let you build both types visually.
Media queries remain essential for responsive design, even with modern layout techniques. The Media Query Generator handles the syntax for standard breakpoints (mobile, tablet, desktop), orientation detection, and newer feature queries like prefers-color-scheme and prefers-reduced-motion.
The CSS Clamp Calculator bridges layout and typography by generating fluid values that scale between breakpoints without media queries. Combined with the Box Model Visualizer for debugging spacing issues and the Aspect Ratio Calculator for consistent media containers, these tools cover the full layout workflow.
