Affichage different sur iphone

Bonjour,

SUR CE SITE :
http://www.dannaprod.com/index.php?static1/videos

sur PC l'affichage des videos est correct.

Par contre sur IPHONE, les videos sont affichées en liste.

Je ne comprends pas pourquoi cet affichage est différent.

Pourriez vous l'aider s'il vous plais ?

je vous remercie
