How to use uncommon tags in html5?

As a front-end developer, when browsing other people’s pages, I always habitually check the source code of their pages and find that most of the website’s pages, including the pages I wrote myself The most commonly used layout elements are nothing more than div, p, span, ul, dl , ol, li, dt, dd, strong, b, whatever it is All effects are composed of these elements.

It’s already 9102, and html5 is already quite mature and standard. Why don’t you use the semantic tags provided by html5 for layout? I personally think it’s because when we first started learning layout, we used the above tags the most. When the new HTML5 tags came out, we had been using div layout for a long time, and maybe we didn’t understand it carefully because we were busy at work. For the application scenarios of these tags, we are still using div layout over time.
