 ## Gutenberg Compatibility
 
-* Gutenberg editor stylesheet – into which has been copy-pasted the typography styles from Bootstrap 4’s _Reboot_ CSS (see [http://getbootstrap.com/docs/4.1/content/reboot/](http://getbootstrap.com/docs/4.1/content/reboot/)).
-	* Note: Blog post and page content in theme’s frontend are controlled by Bootstrap’s columnar grid layout – not by the Gutenberg editor CSS. This means that _b4st does not support Gutenberg’s extra-wide image blocks_.

 ## Child-Theme Friendly
 
 * Many functions are pluggable.
-	* Note: Although b4st was originally intended as a simple starter theme (hence the name **b4st**), several developers wanted child theme capability. So the functions have been made ‘pluggable’. (However, b4st can still be used as a starter theme.)

 * Theme [hooks](/functions/hooks.php) – paired _before_ and _after_ the navbar, post/page main, (optional sidebar) and footer. Parent theme hooks are able to recieve [actions](https://developer.wordpress.org/plugins/hooks/actions/) from a child theme.
