html - Should you, or should you NOT, close void elements/self-closing tags with a forward slash?

Thanks for taking the time to read this.

I have looked at all of the directly relevant questions and answers, and as well as the indirect ones, regarding this topic. And thus far, as far as I can tell, they have not answered the question specifically how I have asked it. Though this is a very fine line here and this question will likely get posted as a duplicate but regardless If I could get the proper answer from any of you I would be immensely grateful.

As of this moment any website that I develop is should I, or should I not, close my void elemnts/self-closing tags. Is this possibly a best practice? E.g:

Anyway, as always thank you for your time and your replies. Have a great day and veterans day weekend.
