+``` +## Main Axis and Cross Axis +Flexbox operates along two axes: the main axis and the cross axis. The main axis is defined by the flex-direction property and determines the +direction in which flex items are laid out, while the cross axis is perpendicular to it. + +## Properties +Flexbox provides several properties to control the layout and behavior of flex containers and items. + +## Common Flex Container Properties +'display': Specifies the type of box used for a flex container. +'flex-direction': Establishes the main axis direction. +'justify-content': Aligns flex items along the main axis. +'align-items': Aligns flex items along the cross axis. +'flex-wrap': Specifies whether flex items should wrap or not. + +## Common Flex Item Properties +'order': Specifies the order of a flex item relative to other flex items. +'flex-grow': Specifies how a flex item grows relative to other flex items. +'flex-shrink': Specifies how a flex item shrinks relative to other flex items. +'flex-basis': Specifies the initial size of a flex item. +'align-self': Allows the default alignment to be overridden for individual flex items. +--- +```html + + + + Flexbox Example + + + +
