I just animating third type of button. Now i have.

.link.type-button - standard button with default, primary and destruct color, small, default and large size, animation on it's back, selectable icon.

.link.type-roll - wierd type of button, with only icon visible and text on hover with some wierd shit animation, selectable icon ofcourse. Various sizes and colors as well.

.link.type-more - More or less static link with right arrow and ofcourse animation on hover.

So one site has three types of buttons with various properties.

And thinking about how overengeneered JS world is.
Fuck you JS world.
