+#### Back/forward cache (bfcache)
 
 [The back/forward cache (bfcache)](https://web.dev/articles/bfcache) allows browsers to instantly restore a page from memory when users navigate using the browser's back or forward buttons.

Because pages are restored in their previous state, bfcache can also help avoid layout shifts that might otherwise occur during re-navigation.
