The Javascript and CSS that comes with Seaside are stored in WAStandardScripts and WAStandardStyles. These classes have methods that returns the scripts and styles as text. Browse WAStandardScripts and WAStandardStyles for examples. Application-specific subclasses of WAStandardScripts and WAStandardStyles can be created. These Javascript and CSS libraries/classes can be added/removed from an application via the application's configuration page.
Component-specific styles can be stored in the method #style. Browse WAStore>>style for an example. The #style method body can be edited either normally in a Smalltalk browser or in the web browser via the Style Editor. To open the Style Editor on a component, Activate the halos by clicking "Toggle Halos" on the toolbar and click on the Style Editor halo (the pencil-like icon) for the appropriate component.
If the CSS or Javascript does to appear to be sent to the client, see here.
