02. The CSS Box Model

The Box Model

The CSS Box Model is a very important concept used to space out elements. The Box model is made out of three main components - the content, padding and margin.

Content
The element within each containing box.
Padding
The spacing between the content and borderline.
Margin
The space outside the borderline.
Margin
Border
Padding
Element Content Area

The border is also part of this model, but it is defined as part of the content.

To visualize how this works, think of how items are packaged.

  • You have your raw item (the content).
  • Then you pad it with packing peanuts, bubble wrap, etc.
  • Then you have your box, which serves as a border to the outside world.
  • Lastly, we have our margin, is the space from the borderline to other elements.

That's it! Just think of all visual element on the page as a box and things will look much simpler.
