Please read this post by Paul O’Brien about the viewport meta tag.
Why is this Code Important in a Webpage? What's the purpose? - #2 by PaulOB
The viewport meta tag does not replace the media queries. Quite the contrary, it enables them.
If you want to read more posts, click the magnifying glass icon at the top of the form page and search for “viewport meta tag”. Do not search this post only.
I have three recommendations for you to consider when writing code
(1) Do not use minimized CSS while developing your site. It makes it difficult to locate properties that may need to be changed.
(2) Use the HTML validator to check for and correct significant errors before posting for help.
(3) SamA74 and PaulOB have given you some excellent advice. Follow the advice given by those who offer to help and tell them what you find. If you don’t understand something, ask then.
I’m not sure how your site is supposed to be used, but I’ll bet it will work better AFTER you add the viewport meta tag in the head of the page.
