Quickly build a layout structure and grab the CSS instead of trial-and-error in a code editor.
Demonstrate layout concepts to students or teammates with an interactive visual tool.
Reproduce a layout problem in the playground to understand which property is causing unexpected behavior.
Flexbox and CSS Grid each have over a dozen properties that interact in non-obvious ways. This playground lets you toggle and adjust every property through visual controls while watching the layout respond in real time. It bridges the gap between reading about justify-content: space-between and actually seeing what it does to a set of child elements.
Flexbox is ideal for one-dimensional layouts (a row OR a column). Grid excels at two-dimensional layouts where you need control over rows AND columns simultaneously.
Absolutely. It's a common pattern to use Grid for the overall page layout and Flexbox for component-level alignment within grid cells.
The gap property works the same way in both: it adds spacing between items without adding space at the edges. In Grid, you can also use row-gap and column-gap independently.
