For now, there are 2 workarounds to theme each portlet but there should be a more straightforward way.
Option 1: to add a united custom theme and use portlet id as css selector in themes stylesheet.
Option 2: ls to there is to wrap the portlet main view as a custom component with ThemableMixin and add a custom stylesheet to this component.
For now, I see two ways of adding this feature:
1)Having the option to add different themes for each portlet.
This approach doesn't work now as there is Vaadin restriction - only one theme is allowed for application (static-bundle).
There could be extra work needed after lifting the restriction, but that needs to be investigated.
2)Adding option to use @CssImport annotation directly on portlet class that extends VaadinPortlet.
Probably that means to extend ThemableMixin for the portlet component underneath.
