Does this have to be uploaded to the server for testing? . I get an error locally.
should be! I didn't open the server before and couldn't see the page effect.
I thought I copied the wrong code and checked it several times, but it still didn't work.
So I copied it twice again, but still couldn't see the effect.
When I was doubting my life, I saw you say this, so I opened the server and looked at this page. The effect was exactly the same as the teacher's.
It's a problem with your code. Let's take a closer look.
