Can't use it with polymer

[MarcosGalaviz]

Hi, I am trying to use this component with polymer but when I run Polymer Build I have this error, I dont know why :(

error: Uncaught exception: Error in plugin 'gulp-htmlmin' Parse Error: <input id="toggle3" type="checkbox" <="" label="">

Toggling the outer inert after toggling the inner inert should not modify its state either.

Clicking the checkbox above will toggle the element's inert property via

element.inert = evt.target.checked == true;

You shouldn't be able to click this or set focus to it..

This inner section is not marked inert

Toggling the inner inert should not make this link become clickable or tabbable.

Toggling the inner inert should not make this fake link become tabbable or clickable either.

Hi, can you modify this code to be the same as yours (there is a fork option)

Feel free to open it again if I'm wrong, but I don't think this is related to my element
