Flexbox arranges items along a single direction, a row or a column, with wrapping onto a new line as a fallback behavior rather than genuine two-axis control, which makes it the right fit for a navbar, a button group, or anything that just needs to distribute or align along one dimension rather than an entire page's rows and columns at once. This tool builds flex layouts visually with direction, wrap, justify-content, and align-items controls, generating CSS for exactly this kind of one-dimensional arrangement.

Useful for building a navbar's item alignment and spacing visually before writing the CSS by hand, distributing a row of buttons evenly without calculating flex values manually, or wrapping a set of items onto new lines with the spacing behavior previewed before copying the code.
