What is postcss-minify-font-values?
The postcss-minify-font-values npm package is designed to optimize font declarations in CSS to ensure they are as short and efficient as possible. It works by minimizing font-weight values, removing duplicate font-family names, and condensing font shorthand declarations where possible.
What are postcss-minify-font-values's main functionalities?
Minifying font-weight values
Converts named font-weight values to their numeric equivalents, reducing the size of the CSS file.
"font-weight: normal;" // Before minification
"font-weight: 400;" // After minification
Removing duplicate font-family names
Eliminates redundant font-family names from the font-family list, making the declaration shorter.
"font-family: Arial, Arial, sans-serif;" // Before minification
"font-family: Arial, sans-serif;" // After minification
Condensing font shorthand declarations
Simplifies font shorthand declarations by removing unnecessary or default values, further reducing CSS size.
"font: italic normal bold 12px/30px Arial, sans-serif;" // Before minification
"font: italic bold 12px/30px Arial, sans-serif;" // After minification

This module will try to minimise the font-family
, font-weight
and font
shorthand
properties; it can unquote font families where necessary, detect & remove
duplicates, and cut short a declaration after it finds a keyword. For more
examples, see the tests.
h1 {
font:bold 2.2rem/.9 "Open Sans Condensed", sans-serif;
}

font:700 2.2rem/.9 Open Sans Condensed,sans-serif
}
p {
font-family: Helvetica Neue,Arial,sans-serif;
font-weight: 400;
