Installing locally

npm i 12-column-grid


yarn add 12-column-grid

To use grids from node_modules -

  • If your project is using SCSS, import grid.scss from node_modules/12-column-grid/src/grid.scss.

  • Projects without CSS pre-processors or other CSS pre-processors can use minified grid.min.css file from node_modules/12-column-grid/dist/grid.min.css.

  • For unminified file, use grid.css from node_modules/12-column-grid/dist/grid.css

  • Angular projects can import the library using angular.json file. Find the assets array in angular.json and put the path to node_modules/12-column-grid/src/grid.scss

        "projects": {
            "<Project Name>": {
                "architect": {
                    "build": {
                        "options": {
                            "assets": [

Using Classes✨

All the class names in this library are same as bootstrap.

The container of the grid items should have a CSS class row or grid.

The width of the grid is divided into 12 columns.

The screen sizes are divided as

Screen type code screen width
πŸ“½οΈ extra large screen xl more than 1200px
πŸ–₯️ large screen lg more than 992px
πŸ’» medium screen md more than 768px
πŸ“± small screen sm more than 576px
πŸ“Ÿ extra small screen xs less than 576px

col classes

Use the following classes for responsive grid layout

  • col-xl-1, col-xl-2, ... col-xl-12

  • col-lg-1, col-lg-2, ... col-lg-12

  • col-md-1, col-md-2, ... col-md-12

  • col-sm-1, col-sm-2, ... col-sm-12

  • col-xs-1, col-xs-2, ... col-xs-12

Mix classes of different screen sizes to get responsive layout

For non-responsive grids use the classes col-1, col-2, col-3, ... col-12.

d-**-none classes

Use the following classes to hide the element for a screen size.

d-xl-none, d-lg-none, d-md-none, d-sm-none, d-xs-none

Aligning grid

Alignment classes can align the grid or the item. When applied to grid item, it aligns the grid item. When applied to the grid, it aligns the grid itself.

For aligning use the classes

  • align-top - align at the top
  • align-bottom - align to the bottom
  • align-right - align to the right
  • align-left - align to the left
  • align-h-center - align the grid horizontally center
  • align-v-center - align the grid vertically center
  • align-h-stretch - stretchs the grid horizontally
  • align-v-center - stretchs the grid vertically


Responsive list of cards

<div class="row">
    <div class="col-xl-2 col-lg-3 col-md-4 col-sm-6 col-xs-12">
        <img src="https://www.imageurl.com/image">
        <h4>image description</h4>

Responsive horizontal navigation links

    nav>ul {
        list-style: none;
    <ul class="row">
        <li class="col-md-3 col-sm-12">
            <a href="#">Link 1</a>
        <li class="col-md-3 col-sm-12">
            <a href="#">Link 2</a>
        <li class="col-md-3 col-sm-12">
            <a href="#">Link 3</a>
        <li class="col-md-3 col-sm-12">
            <a href="#">Link 4</a>

Customizing grids πŸ”§

To customise the library, you need to use SCSS in your application. The following things can be customized -

  • Break points

    $breakPoints :(
        xl: 1600px,
        lg: 1200px,
        md: 1080px,
        sm: 480px,
        xs: 0

    If the keys of $breakPoints are changed then it will reflect in the class names generated. For example, if the key lg is changed to large then the classes col-lg-1, col-lg-2, ... col-lg-12 will change col-large-1, col-large-2, ... col-large-12.

  • Number of columns in the grid

    $gridColumns: 10;
  • Gap between the grid rows

    $gridRowGap: 30px;
  • Gap between the grid columns

    $gridColumnGap: 10px;
  • Prefix .col before all column clases

    $columnPrefix: '.my-company';

Use @import after declaring variables for customizing.
