What are the best practices for CSS and JavaScript?

Some best practices for CSS include using a mobile-first approach, keeping styles modular, and minimizing specificity. For JavaScript, consider using ES6 features, keeping functions small, and avoiding global variables.

Can you explain the mobile-first approach in CSS?

The mobile-first approach means designing for smaller screens first and then progressively enhancing the design for larger screens. This ensures a better user experience on mobile devices.

What do you mean by keeping styles modular?

Modular styles involve breaking your CSS into smaller, reusable components. This makes it easier to maintain and scale your styles.

How can I minimize specificity in CSS?

To minimize specificity, use class selectors instead of IDs, avoid inline styles, and keep your selectors as simple as possible.

What are some common JavaScript pitfalls to avoid?

Common pitfalls include not using 'strict mode', forgetting to handle asynchronous code properly, and not understanding variable hoisting.
