headers not showing on iphones

Hi,
I have migrated the site over to [will include the site in the next private post] to deploy it. It is now live but when I checked on iphones, the headers and rows with videos are not displaying. Please visit the service page and about us page, and portfolio pages to review the problems.
Moreover, on the home page, I have disabled the second row from the top with animations for iphones and tablets but the white gap is still showing.
It seems that none of the HIDE effects are working at all.

Thank you for your prompt reply!
