To use a different built-in set of icons, import `core-icons/-icons.html`, and specify the icon as `:`. For example: You can also create custom icon sets of bitmap or SVG icons. Example of using an icon named `cherry` from a custom iconset with the ID `fruit`: See [core-iconset](#core-iconset) and [core-iconset-svg](#core-iconset-svg) for more information about how to create a custom iconset. See [core-icons](http://www.polymer-project.org/components/core-icons/demo.html) for the default set of icons. @group Polymer Core Elements @element core-icon @homepage polymer.github.io -->
