CSS Flexbox is a one-dimensional layout model that offers an efficient way to align and distribute space among items in a container, even when their size is unknown or dynamic.

Key Flexbox Properties

The most important properties are `display: flex;` on the container, and then `flex-direction`, `justify-content`, and `align-items` to control the layout. For flex items, `flex-grow`, `flex-shrink`, and `flex-basis` give you fine-grained control.

Visualize with Tools

While we don't have a dedicated Flexbox tool yet, you can experiment with its properties in our Live HTML Editor to see the effects in real-time.
