What are some effective debugging techniques for CSS and JavaScript?

There are several techniques you can use for debugging CSS and JavaScript. For CSS, using browser developer tools to inspect elements and view applied styles is essential. For JavaScript, console logging and using breakpoints in the debugger can help identify issues.

Can you explain how to use breakpoints in the debugger?

Sure! In most browsers, you can open the developer tools (usually F12), go to the 'Sources' tab, and find your JavaScript file. Click on the line number where you want to set a breakpoint. When you refresh the page, the execution will pause at that line, allowing you to inspect variables and step through the code.

What about CSS? How can I find out which styles are being applied?

In the browser's developer tools, go to the 'Elements' tab. Click on an element to see its styles in the 'Styles' pane. You can see which styles are applied, overridden, and even toggle them on and off to see changes live.

Are there any tools that can help with debugging?

Yes! Tools like Chrome DevTools, Firefox Developer Edition, and extensions like React Developer Tools can greatly enhance your debugging experience by providing additional insights and features.
