Hmmm... maybe I should have chosen a different acronym. What you expected to see isn't alwasy what you got. WYETSIAWYG Rendering across browsers and operating systems was a trainwreck until maybe 5 years ago (over a decade of polyfill is finally gone). And even with an ecosystem like ElectronJS + Bootstrap, Win10 MacOS and Linux all look slightly different. So yes and no to "DOM was always...", but more "No."
