How to get properties in Polymer content element?

Question

Probably something super easy, but I seem unable to find the answer.

I would like to replace the properties in the <content> section. But I don't understand how to push the title (with content hola ) to the <content> section.

demo-app.html

<dom-module id="demo-app">
  <template>
    <style>
      :host {
        display: block;
      }
    </style>
    <my-el>
      [[title]] or {{title}}
    </my-el>
  </template>
...

my-el.html

<link rel="import" href="../../bower_components/polymer/polymer.html">

<dom-module id="my-el">
  <template>
    <style>
      :host {
        display: block;
      }
    </style>
    <content></content>
  </template>

  <script>
      Polymer({
        is: 'my-el',
        properties: {
          title: {
            type: String,
            value: 'hola',
          },
        }
      })
  </script>
</dom-module>

PS:
I'm 99% sure there are some docs that I'm missing... Any link is welcome :-P

That's technically possible if <demo-app> had its own title property that you bound to <my-el>.title like this:

<dom-module id="demo-app">
  <template>
    <my-el title="{{title}}">
      [[title]] or {{title}}
    </my-el>
    ...

 HTMLImports.whenReady(() => { Polymer({ is: 'my-el', properties: { title: { type: String, value: 'Hello world!', notify: true } } }); Polymer({ is: 'demo-app' }); });

 <head> <base href="https://polygit.org/polymer+1.7.0/components/"> <script src="webcomponentsjs/webcomponents-lite.min.js"></script> <link rel="import" href="polymer/polymer.html"> </head> <body> <demo-app></demo-app> <dom-module id="demo-app"> <template> <style> h1 { color: blue; } </style> <my-el title="{{title}}"> <h1>[[title]]</h1> </my-el> </template> </dom-module> <dom-module id="my-el"> <template> <content></content> <section> <input type="text" value="{{title::input}}"> </section> </template> </dom-module> </body>
