Change Entire Document Text via CSS Injection

To me it would make the most sense to support the same fonts as Microsoft Word, they are open source and to be fair most people convert Word documents to PDF to send them places. Atmos Font makes PDFs look like ransom notes. ThE wOrDs ArE ALL cRa zY. I understand PDFs are incapable of reflow like Word is, but it is a web app on a canvas and it should be able to support CSS injection since it, in and of itself is a web application styled by CSS.  Give us the ability to style the canvas using DIVs and standard CSS.  This would be a fair, reasonable option and if there were the ability to assign IDs that were DIVs under the hood or the ability for blocks of things to be grouped into DIVS, we would not have to manually select, highlight all the text and do this for every blob of text. It would also allow us options to style images, and create additional functionality, calls to action, and provide a a great deal of customization for those willing to invest in learning CSS and be an immediate tool for those of us who already know CSS.  The current process is time-consuming, it sucks and it is unnecessary. Why build the tool, and not support the fonts you know people export work from to convert to PDF,  other than to be contrary,? The product usability weakens and then gets dumbed down making what is an essential part of managing a document, slow, cumbersome, and time-consuming. If nothing will be done about it, why not follow Microsoft builds and then add their fonts so that it is as least usable when we export? I write proposals a lot and they are well-formed Word docs. Changing fonts screws with CSS and other blocks of text placement so its not fun to clean up. I am paying for Creative Cloud and would prefer to use Acrobat so I can turn it into an e-sign doc, but I have to use Windows PDF print driver, save it as a Windows PDF, then import it and move on. Any changes in Acrobat as I go will result in two distinctly different fonts.
