CSS Flexbox Generator - Visual Layout Tool

Container-level flex-direction, flex-wrap, justify-content, align-items, align-content, and gap; each child can be tuned individually for grow, shrink, basis, and self-alignment. CSS is generated instantly as you adjust visually.

Top bar: space-between plus a centered cross axis. Pushing card buttons to the bottom: column direction with an auto top margin. Equal columns: set the items' grow to 1. Prefer gap over propped-up margins for spacing — gap doesn't collapse, sparing you the collapsing and double-margin headaches.

The classic cause is the interaction between basis and min-width: the content's minimum width props the item open, and resetting min-width to 0 is usually the unlock. Also note that grow and shrink both at 0 leaves an item close to fixed-size — exactly what icon columns want.

Use the item-level self-alignment (align-self) instead of changing the container alignment and dragging every item along. The order property can change visual order, but the accessibility reading order may not follow — think it through before relying on it.

Two things: retest wrapping with real content lengths — the short placeholders in the generator will never expose a long title blowing out the row — and add the key breakpoints: narrow screens often need a column direction and tighter gaps, and breakpoints belong in project styles, not in a generator session. For two-dimensional layouts switch to the grid generator, and use a px/rem converter when gaps must land in design tokens.
