Configure a website light
Get the basics right
A website light is a special type of website. The backend (where you manage the content of the site) is Drupal, the frontend (the site as visitors see it) is Vue JS. That is why a website light has two different URLs:
You have to login to the backend to get to the content of the website. You have to use the frontend URL to see the effect of your changes in the backend.
A website light is intended for websites with little content and does not have the extensive configuration possibilities of a fully Drupal website. A lot of components of a website light are predefined and can't be configured to your wants.
