Here is an old article on z-index which may provide some insight: http://yagudaev.com/posts/getting-reliable-z-index-cross-browser/
Specifically: *Another problem is that if the element has no z-index, but its container does, the z-index returned would be auto in all browsers other than IE7, which returns 0. To deal with this situation we need to specify that the z-index should be inherited from the container. We do this by saying z-index: inherit, which will solve our problems in most browsers. IE7 proves to be different, luckly it is different enough that we can write a simple if statement to check if the value returned is zero, if it is, get the value from the parent.* Chris Rockwell On Thu, Jan 22, 2015 at 10:57 AM, Chris Rockwell <ch...@chrisrockwell.com> wrote: > I think if you add a z-index to everything that is position:relative it > will solve the issue (.circle-button, .plant-it).
