I am taking a class on algebraic topology, and this concept was introduced quite quickly: it was the subject of a week's lecture and then we just kept on using it during the exercises. And now I still feel I don't have an intuitive feel for it. I am looking for some reference where CW-Complexes are treated in detail, with as many examples as possible. Thanks in advance!

Hatcher's book (https://www.math.cornell.edu/~hatcher/AT/AT.pdf) is one of my favorite algebraic topology book, it has a lot of examples. For a precise and detailed first exposition on CW-complexes i suggest this book of James W. Vick, Homology Theory An Introduction to Algebraic Topology (https://www.springer.com/la/book/9780387941264) and the book of James R. Munkres Elements of Algebraic Topology (https://books.google.it/books/about/Elements_of_Algebraic_Topology.html?id=FoplRBTu7wwC&redir_esc=y) which give a precise and formal description of the main properties and the inductive construction of CW-complexes.
