Fylgja component - Flex Grid

Create a complete grid using flexbox, and only set the columns you need.

Making it even smaller than other flex grids.

Installation  # 

npm install @fylgja/flex-grid

Then include the component in to your code via;

@import "@fylgja/flex-grid"; // DartSass or LibSass >= 3.6
@import "@fylgja/flex-grid/index"; // LibSass <= 3.5
@import "@fylgja/flex-grid/flex-grid.css"; // CSS or PostCSS

How to use  # 

This grid does not work with a 12 columns or 24 columns layout, unlike other frameworks.

This only makes your CSS bigger with unused columns.

The power of the flex-grid is that for each media query, there are specific amount of columns set.

So for example on mobile you might only need 2 columns. Then you can set the flex-grid to only load 2 columns.

<div class="flex-grid">
<div class="cell sm-2"></div>
<div class="cell sm-2"></div>

Each cell size is 100% divided by $i.

Making it way more clear what size you can set.

And unlike 12 column grid you can set a 5 column grid row.

Since each column you create is based on the 100% divided by $i.

Classes  # 

$mq = @media, e.g. .sm-2 or .lg-2

.flex-grid: Sets the grid and this is also the wrapper class. (required)

.cell: Sets the grid item (required)

  • .${mq}-${1}: the grid item size
  • .${mq}-grow: the grid item size that grows to fit the available space
  • .${mq}-shrink: the grid item size that shrinks to fit the content size

Depends on the booleans set, see config

.-gap: modifier class to set grid gap

.-fill: modifier class to make each cells content equal height, works great with cards and other flexable components.

.offset-${mq}-${i}: set the cell offset, from left.

.cell and .offset Chunks: allow you to create more complex flows.


<div class="flex-grid">
<div class="cell md-3-2">I am taking 2/3 of the space</div>
<div class="cell md-3">I am taking 1/3 of the space</div>

Config  # 

By default the config is set for the smallest use case, so many configs are disabled to load only what is needed.

Booleans  # 

$enable-flex-gaptrueLoad the gap directly without gap class
$enable-flex-fillfalseEnable the fill class
$enable-flex-offsetfalseEnable the cell offset classes
$enable-flex-chunkstrueEnable the cell and offset chunk classes

Setters  # 

$flex-grid-gaps()Additional gaps
$flex-grid-cellsxs 2, sm 3, md 3, lg 4, xl 5Amount of cells, per MQ
$gap-size1remThe default gap size

Breakpoints  # 

All breakpoints are set via the SCSS map $breakpoints. Each point is based on the Bootstrap naming.

See the upcoming @fylgja/core module for more information.

Helper (mixins)  # 

The flex grid is build using a few helper mixins. You can use the helpers if you need a little more than the config can offer you.

flex-grid-mq$mqCreate a mq with if statement
flex-grid-gap$size, $classCreate a grid gap
flex-grid-cells$mq, $iCreate a cell sizes
flex-grid-offsets$mq, $iCreate a cell offset sizes

FAQ  # 

What is mq?

As stated under the section How to use, classes

mq is shorthand for media query.

Why is there a hyphen before some classes?

Some classes are modifier classes, and we wanted to have different naming, to separate them from normal CSS class naming.

In the upcoming framework you will see a little more of this. And we will also add a section to explain our CSS naming convention.

So good stuff to come 😉

Why should I still use a flex-grid instead of a CSS Grid

It's not an valid answer to say browser support, since you can use CSS grid in IE11, via Explicit grid (fixed size).

Flex-grid makes sense for flexable grids, where you don't know the layout before hand.
