I implemented keyboard navigation for my table, and it worked perfectly—until I tried using the mouse. The selected row would stay gray instead of blue, but only when my mouse was hovering over it. A debugging journey through CSS pseudo-class conflicts.
I just made a commit, so why does VS Code still show that asterisk (*) on my branch name? A debugging journey through Git's "deleted" file status and what to do about it.
I was following a tutorial and copied this code: <div class="grid [responsive-columns] gap-6"> and NOTHING HAPPENED! 😱 My grid looked broken and I couldn't figure out why. My mentor pointed out the issue immediately: I copied [responsive-columns] literally as a class name! It was a placeholder meant to be replaced with actual Tailwind classes. This embarrassing moment taught me the crucial difference between documentation placeholders and real code. Never again! 🔥
I just set up my responsive grid container with grid-cols-1 sm:grid-cols-2 md:grid-cols-3 lg:grid-cols-4, but how do I know it actually works? 🤔 It's just an empty container! My mentor showed me a brilliant testing strategy: add colorful placeholder boxes to VISUALIZE the grid! This changed everything. Now I can resize my browser and watch the magic happen in real-time. No more guessing—I can SEE exactly what my users will experience! 🎨✨
"My login endpoint is returning 403 Forbidden! But I configured it as .permitAll() in SecurityConfig! Why is the JwtFilter still blocking it?" I spent 2 hours debugging this. Turns out, I had a fundamental misunderstanding of how Spring Security works. The JwtFilter doesn't "skip" endpoints - it runs on EVERYTHING. Let me explain the magic. 🎩✨
