Absolutely positioned H2 element with 2 child divs collapsing in Safari only

[svoltmer]

I have a CSS animation with an absolutely positioned wrapper H2 element and 2 sibling child divs with text, but the wrapper collapses in Safari and doesn’t honor the child elements inside of it. Is there a workaround? Here is the page with the issue in the header image. Innovation Grove | Rose-Hulman.

*Edit: The issue was resolved by changing the positioning. Removing the "bottom" attribute and replacing it with transform: translateY(-50%);
