The Ultimate CSS Layout Generator

Building responsive UI layouts is the foundation of front-end development. While the CSS Flexbox model has become the industry standard for aligning and distributing space among items in a container, native mobile SDKs implement these concepts using entirely different syntax and paradigms. This generator lets you build your layout visually and automatically translates your configuration into exact CSS code.

Standard CSS Flexbox

The CSS Flexible Box Layout Module (Flexbox) provides a more efficient way to lay out, align, and distribute space among items in a container, even when their size is unknown and/or dynamic. The main idea behind the flex layout is to give the container the ability to alter its items' width/height (and order) to best fill the available space. A flex container expands items to fill available free space or shrinks them to prevent overflow.
