-Depending of the mode, you will need to import in the app sass file:
-
-* Bootstrap 4: `@import "~bootstrap/scss/bootstrap.scss";`
-* Preset webpage: `@import "~grapesjs-preset-webpage/dist/grapesjs-preset-webpage.min.css";`
-* Preset newsletter: `@import "~grapesjs-preset-newsletter/dist/grapesjs-preset-newsletter.css";`
