As a beginner to Webflow, the best way to learn is to copy tutorials like mine and others you find on the internet.
You may not understand every concept in the beginning, and that's completely fine. Just focus on replicating the steps and recreating the same results.
As you start coming across concepts that you want to understand better, start referring to the videos from the Webflow University.
In particular, this this 101 Crash Course on Webflow explains all the basic concepts. Watch individual lessons based on the concept you are currently trying to understand.
I learnt almost everything I know about how to build websites on Webflow from their University.
Seriously, it's that good.
After you build a basic site, go for the next tutorial, which is a Full Site Build on Webflow. It's 4 hours long, but it will probably take you the entire weekend to follow and recreate everything.
Keep doing this and practicing by copying other websites you'll be running in full speed in a matter of weeks!
