Course Introduction：Core points Flexbox is a CSS layout model that allows developers to create complex UIs without relying on redundant CSS and JavaScript tricks. It uses a linear layout model, making it easier to layout content horizontally or vertically without spacing calculations. Flexbox can be used to create websites with giant navigation menus.
