Web design: Which is your favorite UX book for web apps?

There are many great UX books for web apps, but my favorites are The Design of Everyday Things by Donald Norman and The Elements of User Experience by Jesse James Garrett.
Both of these books offer great insights into how to design effective and user-friendly web apps. The Design of Everyday Things is especially useful for understanding how to design for usability and user feedback, while The Elements of User Experience provides a lot of helpful tips on effective interaction design.

CRO & UX are a big field, it can be difficult to know where to start 🤔

Most of the guides out there are either too long, too short, or generalize things so much that they do not help you at all.
