CSS Property

font-weight

Typography

Sets the weight (boldness) of the font.

Syntax

font-weight: value;

Example

font-weight: 700;

Common use cases

  • Bold headings
  • Emphasizing key text
  • Variable font weight control

Practical developer insight

Not all fonts support all weight values — if font-weight: 500 looks the same as 400, your font probably only has regular and bold variants loaded.
