Card Row Microinteractions

Here are two close-ups to highlight the "microinteractions" from my last shot. In this case "microinteractions" is just a fancy word for "hover states". What do you call them?

For this design, and all designs at AWeber, it was important that the hover states were fully accessible. We made sure the colors met the WCAG AA minimum contrast ratio and styled focus states the same as the hover states. Don't forget keyboard users :)
