The two resources I recommend are The Designer of Everyday Things (https://www.amazon.com/Design-Everyday-Things-Donald-Norman/dp/1452654123 https://www.amazon.com/Design-Everyday-Things-Donald-Norman/...) and Designing Interactions (https://www.amazon.com/Designing-Interactions-Press-Bill-Moggridge/dp/0262134748/ref=sr_1_1?s=books&ie=UTF8&qid=1502753508&sr=1-1&keywords=designing+interactions https://www.amazon.com/Designing-Interactions-Press-Bill-Mog...) Both focus on more than website design, but they helped me understand how users interact with my user interfaces. I'm sure there are also a ton of great blog posts out there too, but I found these books the most helpful.
