Is not Compatible with Polymer2.0

[Borjagodoy]

Hi!! I need use your component with polymer 2. I can do a PR with the changes in the code (content = slot) for the compatiblity of the component.

Is a interesting PR by the road map of the component?

If you have a fork with a fix for polymer 2.0, go ahead and make a PR!

I tried to create a Polymer 2 version but the shadow dom v1 spec has limitations
First is webcomponents/shadycss#5

Second is
Selects distributed nodes inside of an element. ::content was renamed to ::slotted but as of yet no browser has shipped the renamed version. It's important to note that ::slotted can only select top-level children, it can't do descendant selectors.

/* Current implementation in Chrome */
::content h1 {
color: red;
}

/* Upcoming implementation in Chrome and Safari */
::slotted(h1) {
color: red;
}

Will need to apply css dynamically but with a certain cost
