Material Responsive Grid

A grid system that adheres to the responsive UI standards outlined for Google's Material Design. The source consists of PostCSS stylesheets that are imported in a specific order and built using postcss-cli.

Installation

npm i material-responsive-grid --save

Grid System

There are three basic elements of this grid system: grids, rows, and columns.

• Rows must be contained by a grid
• Columns must be contained by a row

Breakpoints

This grid system supports six screen sizes:

• Extra-small (4 columns)
• Extra-small (8 columns)
• Small (8 columns)
• Small
• Medium
• Large
• Extra-Large

This follows Google's recommendation for responsive UI breakpoints:

• With the exception of the first three, screen sizes have 12 columns.
• The gutter is either 16 px or 24 px. A 24 px gutter is applied when both screen dimensions are greater than or equal to 600 px.
• Grids will fill the viewport until 1600 px. At this point, the grid can either: continue to fill the viewport or remain 1600 px wide (left aligned or centered).

Classes

Most classes apply to a particular screen size. This relationship is designated by the inclusion of the screen size's abbreviation in the class name:

• Extra-small (4 columns): xs4
• Extra-small (8 columns): xs8
• Small (8 columns): sm8
• Small: sm12 or sm
• Medium: md12 or md
• Large: lg12 or lg
• Extra-large: xl12 or xl

For screen sizes with twelve columns, a duplicate set of classes has been provided that does not include the number of columns in the screen size's abbreviation.

Grids

Grids have the following classes:

• .grid - The main element that contains rows. It has a margin applied that will absorb the row's negative left and right margins.
• .marginless - Eliminates the outer padding that prevents a row's content from spanning edge to edge.
• .fixed-left - Starting at 1600 px, the grid will be fixed width and left aligned in the viewport.
• .fixed-center - Starting at 1600 px, the grid will be fixed width and centered horizontally in the viewport.
• .grid-fixed-left - Deprecated, see .fixed-left
• .grid-fixed-center - Deprecated, see .fixed-center

The default behavior for a grid will be to fill the viewport and preserve outer padding on edge-adjacent columns.

Rows

Rows must be contained by a Grid and have the following classes:

• .row - The element that contains columns. It uses a negative margin that negates the outer gutter of the first and last columns.
• .reverse - Reverse direction of this row.
• .start-{size} - Justify content to the start for the specified sizes (based on direction).
• .center-{size} - Center content within this row for the specified sizes.
• .end-{size} - Justify content to the end for the specified sizes (based on direction).
• .top-{size} - Vertically align content to top for the specified sizes.
• .middle-{size} - Vertically align content to middle for the specified sizes.
• .bottom-{size} - Vertically align content to bottom for the specified sizes.
• .around-{size} - Evenly distribute unused space around columns for the specified sizes.
• .between-{size} - Evenly distribute unused space between columns for the specified sizes.

Columns

Columns must be contained by a Row and have the following classes:

• .col-quarter-row - Consumes a quarter of a row for all screen sizes
• .col-half-row - Consumes half of a row for all screen sizes
• .col-three-quarter-row - Consumes three-quarters of a row for all screen sizes
• .col-full-row - Consumes the full row for all screen sizes
• .col-{size}-{integer, 1-max column count} - Number of columns to consume for a particular screen size
• .col-{size}-offset-{integer, 0-max column count-1} - Number of columns to offset this column for a particular screen size
• .first-{size} - Present this column first for a particular screen size (based on row direction)
• .last-{size} - Present this column last for a particular screen size (based on row direction)
• .hidden-{size}-only - This column will be hidden for a particular screen size
• .hidden-{size}-down - This column will be hidden for screens as wide as or narrower than a particular screen size
• .hidden-{size}-up - This column will be hidden for screens as wide as or wider than a particular screen size

Example

<div class="grid">
   <div class="row">
      <div class="col-xs4-4 col-lg-6">
         <p>This column consumes the entire row for extra-small,
         small, and medium screens.  For large and extra-large
         screens, it consumes half of the row.</p>
      </div>
      <div class="hidden-md-down col-half-row">
         <p>This column isn't visible for extra-small, small, 
         and medium screens, but is visible for large and 
         extra-large screens.  It consumes half of the row.
      </div>
      <div class="hidden-sm-down hidden-up-xl col-md-12">
         <p>This column is only visible for medium and large
         screens and consumes the entire row.</p>
      </div>
      <div class="hidden-sm8-only hidden-sm-only hidden-lg-only col-full-row">
         <p>This column is hidden for small and large screens
         and consumes the entire row.</p>
      </div>
   </div>
</div>
