postcss-ms-grid

Simple and clean postcss plugin for adding css-grid fallback for ie.

Install

npm install -D postcss-ms-grid

Usage

Register postcss plugin in postcss.config.js

module.exports = {
  plugins: [
    require('postcss-ms-grid')
  ]
};

Create grid layout using css grid:

.container {
  grid-template-rows: repeat(3, 1fr);
  grid-template-columns: 1fr 200px 300px;
  grid-column-gap: 10px;
  grid-row-gap: 20px;
}
 
.column1 {
  grid-column: 1 / span 2 / true;
  grid-row: 1 / span 3 / true;
}
 
.column2 {
  grid-column: 3 / span 1 / true;
  grid-row: 1 / span 3 / true;
}

As you can see from the example you can use css grid as you would do it without this plugin. This plugin takes care of adding correct -ms prefixes for IE11 and handles additional columns when row/column gap is defined. Every gap is treated as an additional row/column. You don't have to take this under consideration when defining grid-column or grid-row. Plugin takes care of it automatically.

The only thing you have to remember when using grid-column and grid-row is that you have to add additional / true at the end of rule if your container is using either grid-column-gap or grid-row-gap.

Notes

Please note that this plugin does not support grid-template-areas. Supporting it would add more complexity and final css bundle would be significantly bigger depending of amount elements using css grid in your codebase. This plugin aims for as cleaner and lightweight IE11 css grid implementation as possible, therefor it doesn't support grid-template-areas.
