Feature request: forced active state for buttons

[brandongregoryscott]

Hi there! I love the project and I'm planning to use it in a project I'm working on. One thing that I would love to have is the ability to explicitly render a button in an :active state. There's an example of this in the docs, but it's not clear how this is being done. (The code just shows a <button> element without any attributes)

I think it would be pretty easy to support with a data attribute selector, like button[data-active]: { ... sunken styles }

An official support would be nice; meanwhile you can use the same trick the documentation uses by putting this in your own CSS:

button.active {
  box-shadow: inset -1px -1px #ffffff, inset 1px 1px #0a0a0a,
    inset -2px -2px #dfdfdf, inset 2px 2px #808080;
}

and then using a <button class="active">
