Start with one true shape
Reduce the first idea to a circle, a line, and one generous field of white.
The rule of less
Simple things, clearly made
Let color do one job
Yellow calls attention, red marks the moment, and blue gives the page a steady place to land.
Keep the line generous
A single dark outline gives every element the same friendly weight from header to footer.
Leave room for delight
More margin is not less content; it lets the clearest idea stay with you.
