Hi Ivo... It's me again (and I'm so sorry...)
I use content PRO (joomla) with scroll reveal attribute.
For the page to be displayed, I need to scroll down, like if a point needs to enter the viewport. If I didn't scroll down, the page remains empty.
And second problem, These pages doesn't display at all on an iPhone even if I scroll down...
I put access details on site details...
Thanks for your help.
