What do i do all my html success got deleted

its reset my progress

I am a bit confused as to what you mean, but if you are asking if the code is there, it is indeed. If you partially did the challenge but stopped, it wouldn’t save because challenges themselves don’t save. This is because they are usually very short, so you should be able to redo the challenge and pass it quickly.

Hopefully that somewhat helps! Sorry if I didn’t though.
