Earlier I made a comment as to the problem with the term HTML semantics claiming that none presentational elements would make the term redundant. I also posited elements such as div and span which are considered non- semantics my are in fact semantics in the sense of meaningful.

Tags like <div>,<span> mostly are claiming to be as non-semantics, but semantics tags like <header> <article> have also no affect to content and accessibility at all. So maybe all HTML tags can be claiming as semantics?

Yes all tags are semantics technically speaking in terms of semantic theories of which there are many

Thank you Miss Molly.Learning a lot from your article like there is a need for accessibility in aspect of web engineering.

Thank you so much I believe that it is the first step not the last one or the one we forget to access and accessibility means availability and if our engineering projects are not available to everyone no matter the reason there's not going to be an experience!

After reading W3C documents,I am so touched by the spirit of web accessibility idea.Miss Molly & Sir Tim Berners-Lee created the web is for all people, but when it come to web engineering we learner somehow don’t get this core concept. That a pity.I wii be keep in mind this.
