Whitespace
The deliberately empty space between and around elements, used to group related things, separate unrelated ones, and give content room to be read.
Example usage
“Double the whitespace around the testimonial so it reads as a moment, not a list item.”
Editor’s note
Whitespace is structure, not absence. Proximity is the strongest grouping signal there is — stronger than borders or background colors — and whitespace is how you control it. Cramped layouts usually don’t need more decoration; they need fewer boxes and more space.
