Visual Principles

Layout Basics

Layout is how you arrange elements on a page. Good layout guides the viewer's eye, creates visual hierarchy, and makes content easy to scan.

Visual Hierarchy

Not everything on a page is equally important. Visual hierarchy uses size, weight, color, and position to signal what matters most:

  1. Large, bold headings draw the eye first

  2. Subheadings provide secondary structure

  3. Body text delivers the detail

  4. Captions and labels provide supporting context

If everything is the same size and weight, nothing stands out — and the viewer doesn't know where to start reading.

Whitespace

Whitespace (also called negative space) is the empty area between and around elements. It's not wasted space — it's an active design tool:

  • Increases readability — text with generous line spacing is easier to read

  • Creates grouping — elements closer together are perceived as related

  • Signals importance — more whitespace around an element makes it feel more prominent

  • Reduces cognitive load — a page with breathing room feels calmer and more organized

Grid Systems

Most professional layouts are built on grids — invisible columns that align content into a consistent structure. A 12-column grid is the most common on the web because 12 divides evenly by 2, 3, 4, and 6, giving flexible layout options.
