6. Overcomplicating Selectors

❌ Bad:

.blog-post .entry-title h1 {
  font-size: 24px;
  margin-bottom: 10px;
}

✔ Good:

.entry-title h1 {
  font-size: 24px;
  margin-bottom: 10px;
}

Using long, overly specific selectors can make your CSS code difficult to read and maintain. Instead, try to use more general selectors that can be reused throughout your code.

7. Neglecting CSS Specificity

❌ Bad:

.button {
  color: red;
}

.button.warning {
  color: yellow;
}

✔ Good:

.button {
  color: red;
}

.button.warning {
  color: yellow;
  background-color: #f8f9fa;
}

CSS specificity determines which rule should be applied when multiple rules conflict. Understanding CSS specificity can help you avoid unintended overrides and ensure that your styles are applied correctly.

8. Ignoring Naming Conventions

❌ Bad:

.btn-red {
  background-color: red;
}

.btn-green {
  background-color: green;
}

✔ Good:

.primary-button {
  background-color: red;
}

.secondary-button {
  background-color: green;
}

Consistent naming conventions make your CSS code more readable and easier to understand. Use descriptive names that clearly indicate the purpose of each class or ID.

9. Overlooking Code Optimization

❌ Bad:

body {
  font-family: Arial, sans-serif;
}

body p {
  font-family: Arial, sans-serif;
}

✔ Good:

body, p {
  font-family: Arial, sans-serif;
}

Combining similar selectors can reduce the amount of code you need to write, making your CSS more concise and efficient.

10. Forgetting to Comment

❌ Bad:

/* No comments */
.button {
  color: red;
}

✔ Good:

/* This class defines the styling for buttons */
.button {
  color: red;
}

Comments are essential for explaining the purpose of your code, especially in complex or non-obvious situations. Well-placed comments can significantly improve code readability and maintainability.

By avoiding these common mistakes and adopting better CSS practices, you can write cleaner, more maintainable code that is easier to understand and modify in the future. Remember, good CSS is not just about making your website look great; it's also about writing code that is efficient, scalable, and easy to work with.
