Why did the whole layout fly away after restarting the computer?

Question

css

During operation, the light went out and the computer rebooted. I haven't actually done anything new since the last save, so I wasn't upset. But when I opened the files later, I was horrified. The whole layout is gone, the most banal classes don't work. To return to the previous view, it was necessary to rewrite absolutely everything that was done. Some features just don't work so far. (For example, this one: How to add blur images while scrolling? ) Although nothing has changed after the reboot. What could be the problem? OS X, posted on Brackets.

Answer 1

If the Windows OS crashes, depending on the situation, it can load a previously saved state. And it can be saved even a very long time ago... I suspect that MacOS or Brakets could also automatically recover from a not very "fresh backup"... :(

Answer 2

We open the developer tool and look at what has fallen off in the error console. The question is too vague, there are no those details, so you have to call telepaths :)
