The ACBL (American Contract Bridge League) has a web page for learning bridge. There are links to several web sites that teach bridge as well as links to the ACBL lessions and videos
Everything can be found I YouTube. My search on looking for videos on bridge lead me to Peter Hollands site. He puts out a video almost daily. The teaching videos are generally short videos on 1 topic. A great way to learn in small chunks, and replay the lesson when you need to see it again.
