The font-kerning
CSS property sets the use of the kerning information stored in a font.
/* Keyword values */ font-kerning: auto; font-kerning: normal; font-kerning: none; /* Global values */ font-kerning: inherit; font-kerning: initial; font-kerning: unset;
Kerning defines how letters are spaced. In well-kerned fonts, this feature makes character spacing more uniform and pleasant to read than it would otherwise be. In the image below, for instance, the examples on the left do not use kerning, while the ones on the right do:
Initial value | auto |
---|---|
Applies to | all elements. It also applies to ::first-letter and ::first-line . |
Inherited | yes |
Media | visual |
Computed value | as specified |
Animation type | discrete |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
The font-kerning
property is specified as one of the keyword values listed below.
auto
normal
none
auto | normal | none
<div id="kern"></div> <div id="nokern"></div> <textarea id="input">AV T. ij</textarea>
div { font-size: 2rem; font-family: serif; } #nokern { font-kerning: none; } #kern { font-kerning: normal; }
var input = document.getElementById('input'), kern = document.getElementById('kern'), nokern = document.getElementById('nokern'); input.addEventListener('keyup', function() { kern.textContent = input.value; /* Update content */ nokern.textContent = input.value; }); kern.textContent = input.value; /* Initialize content */ nokern.textContent = input.value;
