The quick brown fox jumps over the lazy dog

Typography is the art and technique of arranging type to make written language legible, readable, and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing, and letter-spacing.

Good typography is measured by how well it reinforces the meaning of the text, not by some abstract scale of merit. Typographic subtlety can be just as important as typographic boldness.

On the Craft of Typography

Typography is the art of arranging type to make written language legible, readable, and appealing when displayed. It involves selecting typefaces, point sizes, line lengths, line-spacing, and letter-spacing.

The Details Matter

Good typography is invisible. Bad typography is everywhere. The reader should never have to fight against the presentation to get to the content. Every choice serves the text.

Typography exists to honor content.— Robert Bringhurst
// Typography scale configuration
const scale = {
  h1: { size: "2.25rem", weight: 600 },
  body: { size: "1rem", lineHeight: "1.65" },
};
