A Dialog UI module based on Material Design Lite
Material Design Lite
Make sure to include the mdl css in your index.html as described here: https://getmdl.io/started/index.html
e.g.
<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
<link rel="stylesheet" href="https://code.getmdl.io/1.3.0/material.indigo-pink.min.css">
You should not include the JS, instead take a look at elm-mdl.
elm package install damukles/elm-dialog
Look at the example and read the module documentation
