Browser DevTools
Browser Developer Tools are your best friend for debugging and inspecting web pages.
This lesson is basically a guided tour explaining what they are and how to use them effectively to understand what's happening in your code.
DevTools? What's that?
DevTools are built right into your browser — no install needed. You just have to right-click anywhere on a page and select Inspect. A whole panel opens up, letting you see the HTML structure of any page, tweak CSS in real time, read error messages, simulate mobile screens, and much more.
And here's the fun part: they work on any website, not just your own. You can inspect how your favorite sites are built, peek at their CSS, and learn from real-world code. It's like having backstage access to the entire internet.
🤝 Can I give you a tour?
It would be incredibly boring to show you screenshots of all the features. Instead, let me give you a guided tour of the most important parts!
