Does anyone has the same problem ? I have read around it seems to be the problem of inline css being rendered difference between client and server .

React attempted to reuse markup in a container but the checksum was invalid

Is there a way to apply a mixin globally?

I don’t think so

You could have a < (global-mixin) I guess if this happens to you a lot

In the README there is one paragraph suggesting you could do something with themes, is this what you want? (Under the header “React context”)
