Hi Yawo,
To be honest it is possible, as always, it depends on your skills and time. As you may noticed Articles have more default styling and elements compare to "naked" page view from SPPB.
So you have to use serveral extra lines of custom CSS.
But I am not sure if this is still a support or customization task (question).
Anyway start from this:
- Disable Article title, author, date it can be done from Articles Options or menu item settings (it's Joomla basic knowledge
- Then for sure you need to add at least those Custom CSS lines:
.view-article article.item {padding: 0; margin-bottom: 0;}
.view-article #sp-main-body > .container
{max-width: 100%; width: 100%; padding: 0; }
.view-artcile .page-header {display: none;}
If this is "black magic" for you I think you have to hire French Front-end Developer with CSS and Joomla skills.
