SuperSlider only loads custom code for that specific post or page. Normally you would have to add code to your style sheet or header in order to call it directly in your content.
If you call Javscript in your content a lot or style your content frequently using CSS, you should find SuperSlider Perpost Code really useful. The plugin works with syntax highlighting plugins too though you will have to delete the content from your database manually if you stop using it as deactivating the plugin won’t remove your data.
