Are you talking about the DOM? The definition of OO typically refers to

I'm talking about the DOM object instead of DOM (Document Object Model). The
"on" event methods meet encapsulation (methods/functions associated to the
object) and polymorphism (different object types support the same interfaces). Since HTML
is a set of internally predefined classes (e.g. body, input and many more). If HTML ever
externalizes classes, then inheritance would become a factor.
This assumes Javascript and CSS are not part of the HTML language.
They're not. They have completely different language standards and can
be used independently of HTML. CSS is used in JavaFX and Android to
style desktop and phone GUIs using a different form of XML.
By this logic, C++ is actually 2 separate languages (C and C++) but no one ever
makes this distinction.
I make the distinction. They are most certainly two separate languages
and evolving in very different directions. I've programmed
professionally in both for 20+ years so I'm fully cognizant of the
differences.
Modern C++ makes heavy use of generics (templates) and over the last
decade is moving towards the functional programming paradigm with
features such as lambda's and algebraic data types.
Do you consider HTML's '<input onclick="some javascript">' fundamentally
different to C++'s 'input::onclick { some C }'? In C++, does C deviate from the C language?
What is it that makes you think C++ is a single language but HTML/javascript/CSS are separate
unrelated languages other than they don't follow traditional concepts?
I don't consider them equivalent.
Up until 2009, JavaScript was not valid outside of HTML.
Mozilla released Rhino way back in 1998.
