Have you tried looking on Youtube? There a lot of beginner strumming lessons, and its good thing to actually see it. It's all about timing, and it can get very complex. Start with the basics and build from there. Also make sure you know the basic chords and can change between them in time to a metronome starting at a slow BPM at first.

The site linked below is a great resource for strumming patterns and has a lot of popular songs to learn with varying difficulty.

Strumming is a very overlooked skill, but I think it can make the difference between a decent guitarist and a brilliant guitarist.

I hope this helps a bit, and good luck!

So which strumming techniques do you need to master to strum like Jimmy Page? His strumming seems so godly.

As said above, YouTube videos. Buy a beginner guitar book and they should go over basic strum patterns. Work on those and eventually you'll be able to hear a song and immediately pick up on the strum pattern even if you don't know the chords being strummed!
