What's that?

postcss-oldschool-grid is a postcss plugin that provide an easy to use and intuitive grid system based on padding gutters and wrapping columns.

No calc(), no right margins with :last-child and :nth-child(), simply nested containers with padding gutters.

Under the hood it behave like Bootstrap grid system, so all you have to do is to put content inside a column, put the column inside a row and eventually put the row inside a wrapper. Easy! :)

Example

Install

First of all you have to install and configure postcss in order to use this plugin: if you don't know what f***ing I'm talking about, take a look to the guide on the postcss github page.

Next step is to use npm to instll postcss-oldschool-grid:

$ npm install postcss-oldschool-grid`

And add it to your postcss processors:

var osg = require('postcss-oldschool-grid');
...
postcss([ osg({config}) ])
...

Options

There are two ways to configure postcss-oldschool-grid:

• Pass an object as parameter when you call the processor

var config = {     
    wrapperWidth: '40px';     
    gutterWidth: '20px',     
    totalColumns: 16
}
...
postcss([ osg(config) ]);

• Set options in the CSS, inside the special at-rule @grid (you can use either camelCase or param-case)

@grid {     
    wrapper-width: 40px;     
    gutter-width: 20px;     
    total-columns: 16
}

totalColumns

Accepted Values: string, number Default Value: 12
