     ### Themes and greater customizability
 
-    People love to customize the look-and-feel of notebooks --- maybe you prefer a sans serif font, more pink 🦄, dark mode, whatever. Notebooks 2.0 allow styling via custom stylesheets. And notebooks are now "full bleed", meaning they extend to the full width of the window rather than being limited to a central column. You can even [animate colorful blobs as the background](./ex/animated-background.html).
