Hierarchy arranges elements by order of importance. It tells the viewer what to look at first, second, and third. A newspaper uses hierarchy: a large headline, a smaller subhead, a smaller byline, and body text. A website uses it too: a bold title, a prominent call-to-action button, and secondary navigation. Without hierarchy, everything competes for attention and the viewer does not know where to start.

Designers create hierarchy with size, color, contrast, position, and spacing. Size is the most obvious. Larger elements read first. Color and contrast are subtler. A bright red button on a gray form pulls the eye. Position matters too. Western readers scan from top left to bottom right, so placing key content along that path helps. White space does quiet work here. Isolating an element with empty space around it signals importance without adding a single line or box.

Tools for building hierarchy

• Scale: bigger elements read first.
• Contrast: strong differences attract attention.
• Color: warm and saturated hues advance.
• Spacing: isolation implies importance.

Hierarchy fails when everything shouts. If every element is bold, large, and colored, nothing stands out. Restraint is what makes emphasis work.
