CSS Flexbox Generator

CSS Flexbox is one of the most powerful layout systems in web design, but configuring flex properties correctly can be confusing when you're managing multiple alignment and distribution rules at once. This tool solves that problem by letting you visually adjust your flex layout in real-time, with an instant preview of how your elements will arrange themselves. Whether you're building a responsive navigation bar, a centered modal, or a complex multi-row component layout, understanding exactly how flex-direction, wrap, justify-content, and align-items interact is essential to modern CSS development.

To use the CSS Flexbox Generator, simply select your desired flex configuration options in the control panel—choose whether items flow row or column, set whether they wrap to new lines, and adjust how items are distributed along the main axis and aligned on the cross axis. The gap control lets you add consistent spacing between flex items without using margins. As you make changes, the live preview instantly shows you how your layout responds, making it easy to experiment with different combinations and find the exact spacing and alignment you need.
