But it doesn't solve the problem with high DPI, changing fonts, and localized strings being sometimes significantly longer, requiring widgets to be resized to accommodate them.
When I click on some languages (I am not native English and my native language, Dutch, is not very high on the list of priorities for most companies) in some of the biggest companies in the world, you notice it just wasn't designed for that. From just making it wrap and enlarge to break the design to simple sticking outside the box.
For some localizations (Chinese for one) you will have to redesign anyway because 'our' (not sure how to describe) designs simply do not work/sell over there.
Most global companies have a local presence doing their local sites; I know some, even inside the EU, very big companies that have a site per country and have the html/css look 'the same-ish' for the user but completely different when you check the source to accomodate for local taste / language.
I like the dream of this working, as I am a programmer, but I don't see it in real life and I find html/css just painful to work with; not difficult but painful compared to most desktop GUI tech. Flexbox etc is changing that a bit but still it looks like people are shoehorning everything in this html5 stuff just because they desperately not want to use/learn other things instead of using the best tool for the job.
Disclaimer: I am old and have seen this before. I do create webapps and use React (new license makes it workable outside hobby projects), but I will gripe about it like the author of the blog post.
Think about user changing the default UI font. OS X and Windows both make it difficult to impossible, and for this exact reason. On Linux, though, it's common and expected (which is probably why all UI frameworks that target it do have some decent dynamic layout support).
But aside from font family, there's also the issue of font size. That one can be cranked up on high-DPI displays, or for accessibility purposes.

Don't get me wrong, I'm certainly not praising HTML5 and CSS here. They're vastly overcomplicated for what they do, for app development. And layouts are a long solved problem in desktop UI frameworks - Qt, Tk, Swing, WPF are just a few examples. WPF in particular is a good example of an XML-based markup language specifically for UI, and it's light years ahead of HTML5 in terms of how easy it is to achieve common things, and how flexible things are overall.
If even half the time and energy invested into building "web apps" (including all the Electron-based stuff) went into an existing UI framework - let's say Qt and QML - we'd all be much better off; developers with far more convenient tools, and users with apps that look and feel native, work fast, and with smaller download sizes (because you aren't effectively shipping the whole damn browser with them).
This is why I had big hopes in XHTML and the XML components, but then we got HTML5 instead, yet another pile of hacks.
I find it fun to write Cocoa apps too, and I do on occasion for throwaway stuff that only I am going to use. But too many people (including me, at home!) simply don't use Macs. When I have to write a portable app, the choices basically come down to GTK+ (doesn't look native anywhere but GNOME on Linux), Qt (requires C++ plus moc and doesn't always look native either, for example on GNOME), or writing everything from scratch for every platform. While the last choice may be the "right" one from a purist's point of view, the extreme amount of work necessary to make duplicate Windows/Mac/Linux (often plus Android and iOS) versions makes it all but out of reach for anyone but big companies.
With the switch to Win32, the tools became VB, Delphi, Smalltalk and Visual C++ with MFC.
Like every Windows developer I also own the Petzold book, bought for Window 3.0 development, and other good one from Sybex, probalby the one book that ever explained how to properly use STRICT and Message Crackers introduced with WIndows 3.1 SDK.
However I might have written about five applications in pure Win32 API instead of using one of the former language/frameworks, as requirement for university projects.
In general, I think many developers only have the bare bones native experience without making use of proper RAD tooling, or the UNIX way, which has always been pretty bad in tooling for native GUIs versus Mac and Windows or even OS/2.
