We should note that all of these places of thermal extremes (Finnish saunas, Japanese hot baths, American beaches and mountains) have their opposites close at hand. There are possibly two reasons for having the extremes right next to each other.
The first is physiological: the availability of extremes ensures that we can move from one to the other to maintain a thermal balance.
The second might be termed aesthetic: the experience of each extreme is made more acute by contrast to the other.
Works of art which have great life often have intense contrast within: rough/smooth, solid/void, loud/silent, empty/full. It is the difference between opposites which gives birth to something. Contrast is what often gives other principles their degree of life – the intensity of the boundary, the markedness of the alternating repetition.
Contrast strengthens centers by making each a deeper entity of itself, and thereby giving deeper meaning to both. It is, at its simplest, what allows us to differentiate. But meaningless contrast remains meaningless. It is only when centers are actively, mutually, and meaningfully composed that it acts to deepen the whole.
A woodworker works along the grain of the wood to prevent splinter. A butcher slices across to the muscle fiber to improve tenderness. A sailor trims the sail to balance the lift and drag from the wind. When we respect the material, the material pays us back in convenience, safety, and efficiency.
Good web design requires the same understanding of and respect for the materials. And that material is the browser, along with its semantic HTML, default styles, and standard behaviors. But the wide use of design software such as Figma, Sketch, and AdobeXD has trivialized the nuances of such material into “canvases” or “artboards” of pre-defined sizes. The convenient styling and manipulation of pixels and objects have disguised the hierarchy of the DOM, the constraints of the device, and the personal preferences and browser setting from real users. Dishonest tools encourage dishonest design.
In the context of web design, Dieter Rams’ principle is not only a resounding criticism against mindless trends and meaningless decorations. It is a humanist reminder to put material honesty and social responsibility above the pursuit of the “pixel perfect” design.
