polymer - How to access shadowRoot for css styling (Polymer1.0) -

-

in polymer0.5 like:

domready: function(){     print(this.shadowroot); }

which print out html in shadowroot.

when same thing in polymer1.0:

ready: function(){     print(this.shadowroot); }

the output null.

more specifically, used access elements css attributes doing:

$(this.shadowroot).find('.some-class').css('height', amount + 'px');

but struggling find out how in polymer1.0, since shadowroot null.

thanks jdepypere hint. turns out of style attributes in style property of node property.

so adjust height:

polymer.dom(this.$.scrollarea).node.style.height = '100px';
