css-fx-layout

This is a lightweight SCSS/CSS only flexbox library inspired by Angular's flex-layout.

Features

This library gives you the option between using data-attributes or CSS classes. Both options give you the same features but the CSS classes can be more verbose when you want a more complex layout. Check out the Wiki for a detailed documentation.

HTML data-attributes

Using the data attributes is the easiest way to use this library:

• data-layout, data-layout-align HTML attributes to be used to control the flexbox container
• data-layout-gap attribute to add margin between the elements in a flex container
• data-hide- and data-show- attributes which can be used to show/hide elements depending on the screen size

CSS classes

Using the CSS classes is more verbose but there are reasons why one might prefer this:

• .fx-layout- and .fx-align- CSS classes to control the flexbox container
• .fx-gap- CSS classes to add margin between the elements in a flex container
• .show- and .hide- CSS classes which can be used to show/hide elements depending on the screen size

Examples

Layout

This is the most simple example. It will make the div a flex container and align the three spans in a row:

<div data-layout="row">
    <span>One</span>
    <span>Two</span>
    <span>Three</span>
</div>

Here's the same example using the CSS classes:

<div class="fx-layout-row">
    <span>One</span>
    <span>Two</span>
    <span>Three</span>
</div>

An advanced example that aligns the items in reverse order with a margin of four pixels and vertically centered:

<div data-layout="row reverse" data-layout-align="start center" data-layout-gap="4px">
    <span>One</span>
    <span>Two</span>
    <span>Three</span>
</div>

The same example using CSS classes:

<div class="fx-layout-row fx-layout-reverse fx-align--start-x fx-align--x-center fx-gap--4px">
    <span>One</span>
    <span>Two</span>
    <span>Three</span>
</div>

Show/Hide

This will hide the first span on phones and show the second span only on desktop sizes. The third span is always visible.

<div>
    <span data-hide-phone>One</span>
    <span data-show-desktop>Two</span>
    <span>Three</span>
</div>

The same example using CSS classes:

<div>
    <span class="hide-phone">One</span>
    <span class="show-desktop">Two</span>
    <span>Three</span>
</div>

Why?

At work I use Angular (and Angular flex-layout) a lot and I've come to like the convenient layout directives Angular flex-layout offers. Recently I found myself creating a plain static website and I wanted to make sure it works without unnecessary JavaScript. As I didn't use Angular or any other JS framework, I had to either layout everything in (S)CSS or create a library that tries to provide a similar experience to what I liked from Angular's flex-layout. This was when I created this.
