I am stuck at the following problem.
On this site that I created, I have a gallery which is located on the bottom of the page. If I hover over the thumbs, they fly a
Few months late on this, but I believe I just encountered this same bug and found a solution. It seems like Microsoft Edge 13 has a problem interpreting some normally acceptable values for transform-origin. Specifically for me, it was ignoring the value right center, but working fine with top left, leading me to believe the center value (which I see in your example code) might be the issue.
The fix for me was to use percentage values, so transform-origin: center bottom would become transform-origin: 50% 100%. Hope this helps anyone else who encounters this issue.
Note that despite the top-voted answer suggesting the ms- prefix, this question is about the recent MS Edge browser, and that prefix has not been required since Internet Explorer 9 for the transform property (per caniuse.com).
