After building the Content Structure (HTML) of your website, the next step in the process is building its Visuals (CSS).

To be able to ease the process of writing the style sheets, we must segment it into levels:

1. Level 1: Default (browser level)
2. Level 2: Normalize (boilerplate level)
3. Level 3: Modify (visibility and sizes level)
4. Level 4: Template (functionality level)
5. Level 5: Theme (custom level)

Ideally, each level must be buildt on top of the previous one yet still independent. For example, leaving the style sheet at browser level must present usable information. The same principle applies as one builds the style sheet level per level.
