Each page explains one principle with a clear definition and the rule to remember.
Scroll through 5–6 real-life before & after examples, each showing the principle in action.
Each page ends with a real-world challenge to practise spotting or applying the principle.

Repeat visual elements to create unity and consistency.
Nothing should be placed on the page arbitrarily.
