block-like markup to export custom html?

[Bill White <billw@wolfram.com>]

I'm using https://github.com/bastibe/org-static-blog to generate http://members.wolfram.com/billw <under-construction.gif>

See especially http://members.wolfram.com/billw/2021-07-05-romanovsky-on-bronstein.html

I have an org file full of these things to denote side-by-side columns of English and Russian text: 

@@html:<div class="grid-container"><div class="grid-child-english">@@ 
Some English text. 
@@html:</div><div class="grid-child-russian" lang="ru">@@ 
Some Russian text. 
@@html:</div></div>@@ 

===> My question: is there a notion of a custom block-like structure that, upon export to html (or whatever backend org-static-blog uses), would insert the inlined html code shown above? I'm imagining something like: 

#+begin_multicol 
Some English text. 
#+break: 
Some Russian text 
#+end_multicol 

to produce this upon export: 

<div class="grid-container"><div class="grid-child-english"> 
Some English text. 
</div><div class="grid-child-russian" lang="ru"> 
Some Russian text. 
</div></div> 

Background: I'm learning Russian and re-learning chess, and one day I realized I could translate articles from old Russian chess magazines. 

Thanks!
