Minimalism

Minimalism is a subtraction discipline, and the list of what it subtracts is short and consistent: decorative rules, background bands, boxes drawn around things that are already grouped, second and third accent colours, a second typeface, and any icon that only repeats the label beside it. What is left has to do the work that the ornament was doing, so hierarchy comes from three things only: size, weight, and distance. A heading is important because it is larger and because nothing is near it.

The lineage runs through the Swiss International Typographic Style and Dieter Rams into Apple’s product pages, and from there into a decade of SaaS marketing sites where a single sentence, one button, and four hundred pixels of nothing became the default hero. It is worth keeping separate from flat design, which the two are often confused for. Flat design is a claim about depth cues (no bevels, no gradients, no shadows) and a flat interface can still be dense and busy. Minimalism is a claim about how much is present at all, and a minimal interface is free to use a shadow if the shadow is the only thing saying that a panel is above the page.

Its failure mode is discoverability, and it is well documented. When the visual signals that mark something as clickable are treated as ornament and removed, people stop finding controls: ghost buttons that read as captions, navigation collapsed behind an icon on a wide screen, grey text on a lighter grey chosen because full contrast looked noisy, icon-only toolbars with no labels anywhere. The honest version of the style removes decoration and keeps affordance, which usually means the restraint is spent on the scenery so the one accent left in the frame can be the thing you are meant to press.

There is also a cost in scrolling. Space is the material, and a page that gives every section room pushes the next section past the fold, so a minimal layout tends to trade overview for calm. That trade is often right for a landing page and usually wrong for a dashboard, which is why the same product frequently ships a minimal marketing site and a dense application behind it.
