Some HTML elements already exist that simplify the creation and use of the custom elements we'll create. The purpose of this chapter is to showcase how to achieve the same functionality with your custom look and feel.

none, one, or any
After creating the components for the above, showcase how we can use them to reconstruct various UI designs. Basic concepts stacked atop each other. Use layout style to showcase how we can display the structure in different ways (value of structure, style, and behavior being distinct).
