The landing page code is located in modules/WPBox/Resources/views/landing/index.blade.php . If you want to do structural changes you can edit those files there. In our updates, we try not to change these files as much as possible. But for just in case, make a backup of them when you have done your changes.

If you want to change the css, the best way to do that will be throughout the option to add custom CSS inside Admin->Setting->CSS and JS. There you can define your own CSS and JS, so if we have an update on our CSS or JS doesn’t discard your changes.

To modify the images, you can do that from Admin->Settings->Images.

To change the text, you can do that via the inline editing tool on the front page if you login as admin.
