Why isn't my CSS working? I've been staring at it for hours!

The Answer: You probably have a typo in your CSS selector or property name! 🤦‍♂️

This happens to everyone. You write what you think is perfect CSS, but there's a tiny typo that breaks everything.

Common culprits:

1. Typos in class names:

   /* You wrote */
   .btn-primray { color: blue; }
   
   /* But your HTML has */
   <button class="btn-primary">Click me</button>
   

2. Missing semicolons:

   .my-class {
     color: red  /* Missing semicolon! */
     background: blue;
   }
   

3. Wrong property names:

   .my-class {
     text-colour: red; /* Should be 'color' */
     font-wieght: bold; /* Should be 'weight' */
   }
   

4. Selector specificity issues:

   /* This is more specific and overrides your styles */
   div.container .my-class { color: green; }
   
   /* Your style gets overridden */
   .my-class { color: red; }
   

How to debug:

1. Use browser dev tools - Right-click → Inspect Element
2. Check the computed styles - See what's actually being applied
3. Look for crossed-out styles - These are being overridden
4. Validate your CSS - Use a CSS validator to catch syntax errors

Pro tip: Use a good code editor with CSS IntelliSense. It'll catch most typos before you even save the file!

Remember: CSS is case-sensitive for class names but not for property names. background-Color works, but .MyClass and .myclass are different! 🎨
