Start with the basic modules on FreeCodeCamp to get the hang of the underpinning technologies and to develop some basic best practices. Then if you have 700 dollars lying around, buy the Webflow Masterclass by Ran Segall to learn Webflow specific best practices. You don’t need a tutor; just make some personal projects and post them here for people to critique your way of doing things.
No problem! The truth is, the more principles you learn, the less time consuming mistakes you’re going to make in the beginning. So I suggest you complete the Responsive Web Design Certificate in full. It says 300 hours but you can finish it in 100. You’ll understand enough to move onto the Webflow University stuff and apply what you’ve learned here.
