HI, Im very new to Javascript and i was wondering if anybody could
please help me with this code. Im not sure what to do:
Use object-oriented JavaScript to model a public library with three
classes: library, shelf, and book. The library should be aware of a
number of shelves. Each shelf should know what books it contains. Make
the book object have "enshelf" and "unshelf"
methods that control what shelf the book is sitting on. The library
should have a method to report all books it contains.
Any help
would be greatly appreciated thanks!

I am somewhat of a beginner/ amateur JavaScript developer and have
created this function by myself which onload should calculate the
client screen dimensions and adjust the width of the div(banner)
accordingly leaving only 5px marginleft and 5px from the right edge of
the screen. As default, I have set the div width as 1177px but this
should change dynamically onload.
