Blog page causing Safari to freeze on iPad and iPhone

Hi all,

I noticed that the blog page below totally locks up my Safari browser on both my iPad and iPhone. The page only partially loads and eventually freezes my browser if I try to click on any page element or Safari button. Do you encounter the same issue on Safari iOS?

Does anyone have any idea why this might be happening? And also how one could fix it?

P.S. This isn’t my blog. Just looking to help and learn.
