...Laravel, Bootstrap & jQuery. Those are all the technologies you need to know, to customize anything in Backpack. You can totally use Vue, React, WebPack, Mix, Less, Sass, NPM etc. If you want to. But you don't have to. Backpack comes with support for multiple Bootstrap themes. If you need to build a custom page, dashboard, or component, you just copy-paste HTML blocks from its website. No designer is required. No pixel pushing.
