Then we’ll likely need to recover some basics. But that’s okay.

$#!% I lost a week to problems on my side. Also, my draft response is gone. Let’s start over with a very simple question—

What are you using for an intro to HTML?

My favorite is W3Schools, but I didn’t start with that. That site tends to leave out explanations for complete beginners, and the pages can change without notice.

Another popular guide is from Mozilla, the makers of the Firefox browser (funded by Google).

https://developer.mozilla.org/en-US/docs/Web/HTML

But Mozilla also skips needed info to cover advanced topics quickly.

Those two sites are meant to act as industry references more than basic instruction for personal projects.

Maybe freeCodeCamp is a better place to start.

Just watch out for the emphasis. The “**” in one of the first page examples isn’t anything but a suggestion of bolding that doesn’t really go in the code.

You’ll want to make sure you can create text on a browser page. Then color or a weblink. Then an image. Then sound. Then see what you can change by creating and linking to a cascading style sheet (CSS).

Only after that (which can take anywhere from a day to weeks depending on how open your learning mind is) do you want to go into the trickier parts for graphic heavy games.
