#spacing-classes

Stylus mixin, inspired by Bootstrap, to add margin and padding css helper classes.

What's it do?

Makes adding padding and margins a class based thing in cases where a custom class is overkill.

Basically: It supplies a bunch of helper classes

see the default output

@media (min-width: 992px) {
 .pad-md-top-3 {
   padding-top: 3px;
 }
 
 .pad-md-left-3 {
   padding-left: 3px;
 }
 
 // ...

}

Installation

$ npm install spacing-classes

Javascript API

spacing classes relies on stylus to work, though included are CSS files that you can pull directly.

var connect = require('connect')
  , stylus = require('stylus')
  , spacingClasses = require('spacing-classes');

// In this case we supply our own sizes.  calling .compile() is optional
spacingClasses.compile({sizes: [1, 3, 5, 7]});

var server = connect();

function compile(str, path) {
  return stylus(str)
	.set('filename', path)
	.set('compress', true)
	.use(spacingClasses());
}

server.use(stylus.middleware({
	src: __dirname
  , compile: compile
}));

Stylus API

To print the classes in a css file:

@import 'spacing-classes'

Customizing

These are the default settings.

Pass one or more of these attributes to spacingClasses.compile().

The following would be identical to not compiling at all ( as they are the defaults ), or compiling with no options.

var settings    = {
  important: false,
  directions: [ 'top', 'left', 'right', 'bottom', '' ],
  sizes:      [ 3, 7, 15, 22, 30 ],
  screens: {
    xs: null,
    sm: 768,
    md: 992,
    lg: 1200,
  },
  types: [
    {key: 'pad', cssType: 'padding'}, // important: true can be added
    {key: 'marg', cssType: 'margin'}, // type.important overrides the settings.important
    {key: 'marg', cssType: 'margin', inverse: true},
  ],
};

spacingClasses = require('spacing-classes')
spacingClasses.compile(settings);

inverse: true (optional)

Note the inverse: true on the 3rd type.

add -inv to the end of a margin class to get negative amounts

marg-xs-top-3-inv {
  margin-top: -3px
}
