Exactly. I put together a demo a few years ago that employed somewhat novel interaction design to showcase some machine learning tech. A number of people were gobsmacked by it and asked endless questions about what framework it was built with. I didn't use a framework. I dug into the deep recesses of CSS to make it do what I wanted. Really, you can accomplish almost anything with HTML/CSS/JS/SVG (though I'll admit it might be painful).
