The font-weight CSS property sets the weight (or boldness) of the font. The weights available depend on the font-family that is currently set.
Values
normal Normal font weight. Same as 400. bold Bold font weight. Same as 700. A value between 1 and 1000, both values included. Higher numbers represent weights that are bolder than (or as bold as) lower numbers. This allows fine-grain control for variable fonts. For non-variable fonts, if the exact specified weight is unavailable, a fallback weight algorithm is used — numeric values that are divisible by 100 correspond to common weight names, as described in the Common weight name mapping section below. lighter One relative font weight lighter than the parent element. Note that only four font weights are considered for relative weight calculation; see the Meaning of relative weights section below. bolder One relative font weight heavier than the parent element. Note that only four font weights are considered for relative weight calculation; see the Meaning of relative weights section below.
Fallback weights
If the exact weight given is unavailable, then the following rule is used to determine the weight actually rendered: •If the target weight given is between 400 and 500 inclusive: •Look for available weights between the target and 500, in ascending order. •If no match is found, look for available weights less than the target, in descending order. •If no match is found, look for available weights greater than 500, in ascending order. •If a weight less than 400 is given, look for available weights less than the target, in descending order. If no match is found, look for available weights greater than the target, in ascending order. •If a weight greater than 500 is given, look for available weights greater than the target, in ascending order. If no match is found, look for available weights less than the target, in descending order.
Meaning of relative weights
When lighter or bolder is specified, the below chart shows how the absolute font weight of the element is determined. Note that when using relative weights, only four font weights are considered — thin (100), normal (400), bold (700), and heavy (900). If a font family has more weights available, they are ignored for the purposes of relative weight calculation.
