Ipod Viewport Bug

So I built this site using viewport height as a measure for different sections of the page. Everything works great except on an ipad. It looks like ipads have a bug where they can’ calculate the viewport height properly. As a result, the pages scroll infinitely.

Googling around, you can find quite a bit of frustration around this issue. https://www.useragentman.com/blog/2014/09/24/fixing-cross-browser-issues-with-css3-viewport-units-in-ie9-and-safari-for-ios/

Has anyone tried to solve this issue with a wordpress site?

Here’s the site with the issue… pull it up on an ipad to see. 5giants.com
