How Can I Master the Horizon Theme in 2025 to Become a Pro Shopify Developer?

Hello amazing Shopify community!

I’m a newbie developer with a burning passion for web development, and recently I’ve taken a deep interest in Shopify theme development, especially the new Horizon Theme 2025.

I know this might sound ambitious as a fresher, but I truly want to master this theme and level up to become a Shopify developer pro, especially in the area of custom theme creation and optimization.

Right now, I feel a bit overwhelmed by the depth of Liquid, theme architecture, and best practices. But I’m here with a humble heart and a strong willingness to learn.

So I’d love to ask:

What are your top tips, learning resources, or personal insights that helped you master Shopify themes (especially Horizon)?
Are there common mistakes to avoid when starting out with theme development?
If you were in my shoes, what would you focus on learning first?
Any advice, links, YouTube channels, courses, or GitHub repos — I’d deeply appreciate it all. ‌‌

Thank you in advance to anyone willing to share a bit of your wisdom. This journey feels tough, but with this community’s support, I believe I can make it! ‌‌

A grateful fresher trying to grow‌‌

The Shopify Skeleton Theme would be a valuable theme to use as a testing theme for building your own components.

And here’s some great YouTube channels:
