jonathantnealPostCSS Short Position 
PostCSS Short Position lets define sides within the position property in
CSS.
.header {
position: fixed 0 1em *;
}
/* becomes */
.header {
top: 0;
right: 1em;
left: 1em;
position: fixed;
}
The position declaration can be extended with the 1-to-4 syntax to target
top, right, bottom, and left. Sides can be omitted using the skip token.
Usage
Add PostCSS Short Position to your project:
npm install postcss-short-position --save-dev
Use PostCSS Short Position to process your CSS:
const postcssShortPosition = require('postcss-short-position');
postcssShortPosition.process(YOUR_CSS /*, processOptions, pluginOptions */);
Or use it as a PostCSS plugin:
const postcss = require('postcss');
const postcssShortPosition = require('postcss-short-position');
postcss([
postcssShortPosition(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

Options
prefix
The prefix option defines a prefix required by properties being transformed.
Wrapping dashes are automatically applied, so that x would transform
-x-position.
postcssShortPosition({ prefix: 'x' });
.header {
x-position: fixed 0 1em *;
}
/* becomes */
.header {
top: 0;
right: 1em;
left: 1em;
position: fixed;
}
skip
The skip option defines the skip token used to ignore portions of the
shorthand.
postcssShortPosition({ skip: '-' });
.header {
position: fixed 0 1em -;
}
/* becomes */
.header {
top: 0;
right: 1em;
left: 1em;
position: fixed;
}
