width: inherit is unusual. Do you actually need two containing divs, or can you
just style :host as needed?

element box is needed for "layout horizontal".

+#titleContainer {
+  color: rgba(0, 0, 0, 0.87);

+  font-size: 13px;

what are these font-weight values overriding?

[Alexander Alekseev, 2016/08/19 06:00:05]

The idea was to exactly follow the design: if font is specified for the element,
let's set it for this element. So that it would stay the same whatever changes
above are made.
