Is it possible to save div with pictures, formatting to phone?

Question

PHP

The question is chaotic because the idea was born spontaneously... Let's
imagine I fill a certain div with some content.. structured text.. pictures.
What are the options-possibilities:
1) stupidly copy and paste into Word (in my opinion everything flies and pictures)
2) export to Word or pdf save .. this is understandable and feasible.
3) save "to the phone" - here xs .. everything is different for everyone ..
4) make a simple application for the phone? I'm still even afraid to think about it ..
5)???...
Roughly speaking, you need to save your favorite article to your gadget in order to use it offline in a beautiful way .. make a selection of such articles ..
P.s. while writing .. I understand that you can’t do without your own application, well, or look for a "partner" .. who already provides such functionality and is cross-platform ...
