问题 Problem: I created a static page view (in its own view folder) that demos the new Sakura.css framework. The framework comes with four CSS themes. I want to be able to select a theme from a list of links and reload the same view with the associated CSS theme file via the controller. I also need the view to default to the 'standard.css' theme.
