Lightroom classic on Mac to web

[Jenna243213395637]

When going from my Lightroom classic on my Mac then logging on web browser none of my pictures, presents, nothing at all is there. 
Why is this happening? Do I need to sync? Have I never saved anything correctly? Please help. I'm trying to learn how to do a proof gallery to my clients and steps are saying to do it through Lightroom web browser

Lightroom-Classic does not automatically 'Sync' photos. You need to-

1) Add photos to a Standard Collection in LrC

2) Mark this Collection to Sync.

3) Turn on Sync from the Cloud icon in LrC.
