The visual language of 3columns is restrained so that the publication can carry the character.
Typography
System fonts, a readable measure, clear heading levels, and modest metadata create a calm reading rhythm.
Color
Black, white, gray, and a precise blue establish hierarchy without competing with the text.
Spacing
One-pixel rules and consistent gutters separate responsibilities. Whitespace is structural: it tells readers which material belongs together.
Editorial conventions
Prefer descriptive titles, short decks, meaningful excerpts, and links that tell the reader where they lead.
