Understanding CSS Flexbox Layouts

The Flexible Box Layout (Flexbox) module provides a highly efficient way to lay out, align, and distribute space among items in a container, even when their size is unknown or dynamic.

Playground Guidelines

Main vs. Cross Axis: `justify-content` controls alignment along the main flex direction axis, while `align-items` governs placement across the perpendicular cross axis.
Responsive Wrapping: Enable `flex-wrap` to allow items to flow naturally onto subsequent lines on smaller screen viewports.
