What are the potential pitfalls of editing PHP code for button customization?

Potential pitfalls of editing PHP code for button customization include introducing syntax errors, breaking functionality, and making the code harder to maintain. To avoid these issues, it is recommended to create a separate CSS file for button styling and use classes or IDs to target the buttons for customization. 

// Example of using a separate CSS file for button customization
// In your PHP file
echo '<button class="custom-button">Click me</button>';

// In your CSS file
.custom-button {
  background-color: blue;
  color: white;
  border: none;
  padding: 10px 20px;
  border-radius: 5px;
}
