i’m a noob, how to upload my live preview html5 portfolio by hosting at “0.s3.envato”

When you upload the item at upload item page ( also previews ) the images are automatically uploading to s3 server
You cannot access the server directly

actually, i have no hosting to upload my live preview for HTML5. what should i do?

Are you on a low budget? There’s plenty of cheap hosting services out there, for sometimes less than $1 USD per month. You just have to search for them.

(And then of course you’ll also need to know how to use FTP, but there’s plenty of YouTube tutorials for this, and most hosts have tutorials too)
