Hey Dean,
Here's my attempt at styling the DPLA widget.

*I've found that including a strictly defined height and width is the way to go to ensure the widget maintains the right layout, even if it's not especially in line with responsive design ideas. It's not that big, so it still fits on small screens.

*There's an image file included now, and a corresponding update to the JS to include it in the widget.

Everything else in the CSS file is for styling and/or locking down styling.
