# Material Design Components in Elm

Port of Google's
[Material Design Lite](https://www.getmdl.io/)
CSS/JS implementation of the
[Material Design Specification](https://www.google.com/design/spec/material-design/introduction.html).

Live demo 
[here](https://debois.github.io/elm-mdl/).

MDL is implemented primarily through CSS, with a little bit of Javascript
adding and removing CSS classes in response to DOM events. This port
re-implements the CSS parts in Elm, but relies on the CSS of MDL verbatim.

*CAUTION*! This is an early and incomplete prototype. Use at your own risk.


### Get Started

Build the demo:

    > elm-make examples/Demo.elm

This will construct a file `index.html`; open that in your browser.

The library has a tiny native component (for measuring geometry of rendered
  elements, a necessity for re-implementing MDL ripple-animations), and so
  cannot be in the elm-package library. If you wish to use the library, I
  know no better way than to copy `Material.elm` and `Material/*` to your
  own project. 

### Embedding in your own HTML. 

Initial page load of the demo will produce a flicker, which can only be 
avoided if you set up the MDL css to load before elm does. Use the file
`page.html` as a template. To build the demo in this mode, comment out 
[line 154 in `examples/Demo.elm`](https://github.com/debois/elm-mdl/blob/master/examples/Demo.elm#L154)
and build the demo like this: 

    > elm-make examples/Demo.elm --output elm.js

This will produce a file `elm.js`. Open the file 
[`page.html`](https://raw.githubusercontent.com/debois/elm-mdl/master/page.html) in your 
browser; this file will set up MDL css and load `elm.js`.

### Contribute

Please do! The easiest place to start is to add more CSS-only components. These require no porting of Javascript, just putting together css-classes as instructed by the [MDL Component Documentation](https://www.getmdl.io/components/index.html). Take a look at

 - [Shadows](https://github.com/google/material-design-lite/tree/v1.1.2/src/shadow)

Progress bars are pure CSS, and spinners seem to use Javascript only to insert
auxiliary DOM-nodes on initialisation.

 - [Loading](https://www.getmdl.io/components/index.html#loading-section)

The remaining components, use Javascript
in various ways. Toggles seem to use Javascript exclusively to insert ripple-animations and __might__ be easy to implement using the `Ripple.elm`
component:

The rest I haven't looked at; they may or may not be straightforward to port
to Elm.
