CSS Reference Guide: flex

The CSS flex property is a shorthand method for setting the flex-grow, flex-shrink, and flex-basis properties on flexible items, which determines their alignment and flexibility within parent containers. The flex-grow property defines how much a flex item will grow relative to other items in the container when there is available space, while flex-shrink specifies how much it will shrink relative to others when space is limited. Flex-basis sets the initial size of a flex item before it grows or shrinks, and it can be expressed as a length, percentage, or the keyword 'auto.' The flex property can be defined using one, two, or three values, with each configuration having specific rules for how the values are interpreted, allowing for flexible and responsive design layouts.
