[IPython-dev] Applying arbitrary CSS to an IPython 3.0 widget

Here's the only usage as I found in the source:
container = Box(_dom_classes=['widget-interact'])

https://github.com/ipython/ipython/blob/0c6a0f7982d430b3e4ff55c1fa04aca58a4fdb16/IPython/html/widgets/interaction.py#L184

Looks like each tuple member is a triple of (selector, property, value):

txt = widgets.Text(value="Stratocaster")
display(txt)
txt._css = [
  ("input", "font-family", "Comic Sans MS"),
  (None, "transform", "matrix(1, -0.2, 0, 1, 0, 0)")
]

Pretty slick!
