What is Flexbox?

• Flexbox = Flexible Box
• "CSS3 Flexbox was designed as a one-dimensional layout model, and as a method that could offer space distribution between items in an interface and powerful alignment capabilities." by Mozilla

Terms

• There are many layers of web, from the picture below, the box is separated into “container（容器）” and “item（項目）.”
• Axes: main axis = inline; cross axis = block
