I'm on Android so I don't have any trouble, but keep in mind that all "browsers" on iOS are just Safari with a skin and a few features bolted onto it. Apple doesn't allow different browser engines on their platform because of various reasons.

It seems to be using the default simple blogger theme so there's probably no point of contact for the website, it's Google after all. The best chance you have is to submit a bug report with Apple about Safari not rendering the page right.
