Flexbox Playground
Visually configure a CSS flexbox container and copy the generated CSS
Flex settings
Examples
Centered hero section
.flex-container {
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
flex-wrap: nowrap;
gap: 16px;
}Centers items both horizontally and vertically — the classic pattern for a hero or modal.
Responsive wrapping card gallery
.flex-container {
display: flex;
flex-direction: row;
justify-content: flex-start;
align-items: stretch;
flex-wrap: wrap;
gap: 24px;
}Cards wrap to new rows automatically and all stretch to the same height, ideal for a responsive grid of equal-height cards.
Details
CSS Flexbox is a one-dimensional layout model that makes it easy to align and distribute space among items in a container. This playground lets you tweak all the major flex-container properties — direction, justification, alignment, wrapping, and gap — and see numbered items react in real time. Everything runs locally in your browser; no data is ever sent anywhere.
About this tool
