Equivalent of typedef in C#
...c.List<Customer>;

Not really. You should let your...
Black transparent overlay on image hover with only CSS?
...t;/div>
As for the CSS, set optional dimensions on the .image element, and relatively position it. If you are aiming for a responsive image, just omit the dimensions and this will still work (example). It's just worth noting that the dimensions must be on the parent element as opposed to the img...
