I wrote the

<img src="images/home.png" id="1">
<img src="images/home.png" id="2">
<iron-icon icon="maps:hotel"></iron-icon>

then it becomes

<a images="" home.png"="" id="1" href="http://....&gt;&#10;                &lt;img src=">
<img src="images/home.png" id="2">
<iron-icon icon="maps:hotel"></iron-icon> </a>

Did you find the solution?

The documentation does not show how to use for example <iron-icon icon="social:mood"></iron-icon>

How does one use an icon from Communication, Device, Editor for example?

For us the solution to this problem was to import the required icon sets.

Before:

import '@polymer/iron-icons/iron-icons.js';

After

import '@polymer/iron-icons/iron-icons.js';
import '@polymer/iron-icons/social-icons';
