I'm producing my website I started using Flash with HTML5. I opened the file in the Animate and when test CTRL + Enter the site appears in the browser. When I publish the site it does not show anything.
Yes. That's what Publish does. It publishes the current document.
I'm going to assume that you mean to say that when you publish, and then open the HTML file, nothing shows. It's because you've used spritesheets, and the associated JSON file isn't allowed to load under local file security. It will work fine when you put the files on your server.
