We are sorry but we also don't know why is that because we we are not web developer and we didn't built this site. You or your developer probably used html tags without knowledge and that's why you have bugs in the code right now.
I recreated similar page step by step and found what causes the issue. One of the hyperlink affected all the below elements. After i remove it it became okay. the hyperlink was in the column element.
If anyone see similar issue in the forum can try this solution.
That's very weird. Maybe you should to try use same link on other page with some content below the link to make sure if this happens on this page only or on any other.

Please open your website in Firefox html mode (CTRL+U) and check html errors you got. Please fix them first and all should be fine.
P.S. Anticipating your question, yes, those errors are not associated with theme and were made by you or one of your extra plugins.
Thanks!
