I have two forked sandbox in codesandbox.io. Although these two sandboxes forked from different places, but I have modified them to use the same package and content.
I wonder why the output results of these two codesandbox are different.
First forked sandbox url. forked codesandbox 001
Second forked sandbox url. forked codesandbox 002
Updated
I did not notice that there is an index.css inside the internal resources (hard to notice if careless), which caused the difference. Thank you @User28 for your reminder.
