Theoretically, it's not a bad point of view, but for a newbie, it's not how the concept "MVC" is normally used. I would suggest linking to something like this: http://guides.rubyonrails.org/getting_started.html#the-mvc-a... - Now, Rails isn't the only way to do MVC, but it's more or less the de-facto standard, so it's good for understanding the basic concepts.

I don't think it makes sense to consider HTML-CSS-JS as a triad on par with MVC anyway. CSS and HTML are very intimately related, so I think it makes most sense to consider them two parts of one technology. JS is more separated and generally takes different skills than HTML/CSS.
