Flexbox is a CSS layout model that provides an efficient way to align and distribute space among items in a container, even when their sizes are unknown or dynamic.
justify-content aligns items along the main axis (horizontal by default), while align-items aligns them along the cross axis (vertical by default).
Use Flexbox for one-dimensional layouts (row OR column). Use CSS Grid for two-dimensional layouts (rows AND columns simultaneously).
