Lost the code format, what could be the reason?

I store the data in database, but sometimes the code format looks wrong, when I refresh the page it looks good, what could be the reason?

We can't help you unless we know more about how your code differs from ours. Can you share enough information for us to understand what's going on? A code sandbox that demonstrates the issue is the gold standard, although not always possible.
