Layout Grid
Material design’s responsive UI is based on a column-variate grid layout. It has 12 columns on desktop, 8 columns on tablet and 4 columns on phone.
Design & API Documentation
Installation
npm install @loipham/material-layout-grid
Usage
HTML Structure
<div class="mdc-layout-grid">
<div class="mdc-layout-grid__inner">
<div class="mdc-layout-grid__cell"></div>
<div class="mdc-layout-grid__cell"></div>
<div class="mdc-layout-grid__cell"></div>
</div>
</div>
Nested grid
When your contents need extra structure that cannot be supported by single layout grid, you can nest layout grid within each other. To nest layout grid, add a new mdc-layout-grid__inner
to wrap around nested mdc-layout-grid__cell
within an existing mdc-layout-grid__cell
.
The nested layout grid behaves exactly like when they are not nested, e.g, they have 12 columns on desktop, 8 columns on tablet and 4 columns on phone. They also use the same gutter size as their parents, but margins are not re-introduced since they are living within another cell.
However, the Material Design guidelines do not recommend having a deeply nested grid as it might mean an over complicated UX.
<div class="mdc-layout-grid">
<div class="mdc-layout-grid__inner">
<div class="mdc-layout-grid__cell">
<div class="mdc-layout-grid__inner">
<div class="mdc-layout-grid__cell"><span>Second level</span></div>
<div class="mdc-layout-grid__cell"><span>Second level</span></div>
</div>
</div>
<div class="mdc-layout-grid__cell">First level</div>
<div class="mdc-layout-grid__cell">First level</div>

CSS Classes
CSS Class | Description
--- | ---
mdc-layout-grid
| Mandatory, for the layout grid element
mdc-layout-grid__inner
| Mandatory, for wrapping grid cell
mdc-layout-grid__cell
| Mandatory, for the layout grid cell
mdc-layout-grid__cell--span-<NUMBER_OF_COLUMNS>
| Optional, specifies the number of columns the cell spans
mdc-layout-grid__cell--span-<NUMBER_OF_COLUMNS>-<TYPE_OF_DEVICE>
| Optional, specifies the number of columns the cell spans on a type of device (desktop, tablet, phone)
mdc-layout-grid__cell--order-<INDEX>
| Optional, specifies the order of the cell
mdc-layout-grid__cell--align-<POSITION>
| Optional, specifies the alignment of cell
mdc-layout-grid--fixed-column-width
| Optional, specifies the grid should have fixed column width
mdc-layout-grid--align-<GRID_POSITION>
| Optional, specifies the alignment of the whole grid
mdc-layout-grid__cell--span-<NUMBER_OF_COLUMNS>
You can set the cells span by applying one of the span classes, of the form mdc-layout-grid__cell--span-{columns}
, where {columns}
is an integer between 1 and 12. If the chosen span size is larger than the available number of columns at the current screen size, the cell behaves as if its chosen span size were equal to the available number of columns at that screen size. If the span classes are not set, mdc-layout-grid__cell
will fallback to a default span size of 4 columns.
mdc-layout-grid__cell--span-<NUMBER_OF_COLUMNS>-<TYPE_OF_DEVICE>
The same as mdc-layout-grid__cell--span-<NUMBER_OF_COLUMNS>
but for a specific type of device(desktop
, tablet
or phone
).
mdc-layout-grid__cell--order-<INDEX>
By default, items are positioned in the source order. However, you can reorder them by using the
mdc-layout-grid__cell--order-<INDEX>
classes, where <INDEX>
is an integer between 1 and 12.
Please bear in mind that this may have an impact on accessibility, since screen readers and other tools tend to follow
source order.
mdc-layout-grid__cell--align-<POSITION>
Items are defined to stretch, by default, taking up the height of their corresponding row. You can switch to a different
behavior by using one of the mdc-layout-grid__cell--align-<POSITION>
alignment classes, where <POSITION>
is one of
top
, middle
or bottom
.
mdc-layout-grid--fixed-column-width
You can designate each column to have a certain width by using mdc-layout-grid--fixed-column-width
modifier. The column width can be specified through sass map $mdc-layout-grid-column-width
or css custom properties --mdc-layout-grid-column-width-{screen_size}
. The column width is set to 72px on all devices by default.
mdc-layout-grid--align-<GRID_POSITION>
The grid is by default center aligned. You can add mdc-layout-grid--align-left
or mdc-layout-grid--align-right
modifier class to change this behavior. Note, these
modifiers will have no effect when the grid already fills its container.
Sass Mixins
Mixin | Description
--- | ---
mdc-layout-grid($size, $margin, $max-width)
| Generates CSS for a grid container on certain device type
mdc-layout-grid-inner($size, $margin, $gutter)
| Generates CSS for a grid cell wrapper on certain device type
mdc-layout-grid-cell($size, $default-span, $gutter)
| Generates CSS for a grid cell on certain device type
mdc-layout-grid-fixed-column-width($size, $margin, $gutter, $column-width)
| Generates CSS for a fixed column width container on certain device type
mdc-layout-grid-cell-order($order)
| Reorders a cell inside a grid
mdc-layout-grid-cell-align($position)
| Aligns a cell vertically inside a grid
mdc-layout-grid($size, $margin, $max-width)
Generates CSS for a grid container on certain device type. The mixin takes three parameters:
$size
: the target platform:desktop
,tablet
orphone
.$margin
: the size of the grid margin.$max-width
(optional): the maximum width of the grid, at which point space stops being distributed by the columns.
mdc-layout-grid-inner($size, $margin, $gutter)
Generates CSS for a grid cell wrapper on certain device type. The mixin takes three parameters:
$size
: the target platform:desktop
,tablet
orphone
.$margin
: the size of the grid margin.$gutter
: the size of the gutter between cells.
mdc-layout-grid-cell($size, $default-span, $gutter)
Generates CSS for a grid cell on certain device type. The mixin takes three parameters:
$size
: the target platform:desktop
,tablet
orphone
.$default-span
(optional, default 4): how many columns this cell should span (1 to 12).$gutter
: the size of the gutter between cells. Be sure to use the same value as for the parent grid.
Note even though size is passed in as one of the arguments, it won't apply any
media-query
rules. It is set for using the correct CSS custom properties to overriden the margin and gutter at runtime (See Margins and gutters section for detail).
mdc-layout-grid-fixed-column-width($size, $margin, $gutter, $column-width)
Generates CSS for a fixed column width container on certain device type. The mixin takes four parameters:
$size
: the target platform:desktop
,tablet
orphone
.$margin
: the size of the grid margin.$gutter
: the size of the gutter between cells.$column-width
: the width of the column within the grid.
