Blank screen in the preview

whenever I want to open preview it is just blank I am not sure if this is bug in code or what? this is in both the preview and live site.

You just haven’t written anything in the index.html file.

I did, I wrote a program in the index.html

I can’t see it in the project, did you apply it to the Glitch editor? Make sure it’s not inside any directory

nvm I think it is working now there were two index.html code was in wrong one

lol it happens

nothing in index.html
