The blank 3 inch by 2 inch screen to the right in previous article

It's not just on your computer it's on every computer that loads this particular article. Why?

I'm not sure.

But, when you quote certain articles and give credit to who wrote that article all sorts of crazy things can happen.

Also, I don't compose my site directly in HTML I compose in what is called "Compose" at blogger.com which basically means in this mode there are automatic HTML compatible robotic coders that do all the coding for me. But, every programmer uses his own methods which might be HTML, might be Java Script or literally ANYTHING else compatible with HTTP or HTTPS. So, because of this almost anything can and will happen in a programming sense when multiple languages and programmers are involved in anything and then run through an automatic robotic coder on top of all this.

So, could I remove this 3 inch by 2 inch blank screen?

Probably yes.

But, it might take me and hour or two of my time which I just don't think is worth it, do you?

1st I would have to get an HTML code copy of what I'm quoting and then try to search for what is creating the blank box (which is likely a little version of the main video at the article) and then I would have to find what removed the little box without disabling the big video box in this article so it wouldn't show up here on my site.

Which might also unravel the whole programming to be able to view the article here at this site.

Would it? Unknown unless I reverse engineered the software and tested it here at this site.
