What are some potential pitfalls of not using placeholders in HTML?

Not using placeholders in HTML forms can lead to confusion for users as they may not know what information is expected in each input field. This can result in incorrect data being entered or users abandoning the form altogether. By using placeholders, you can provide clear instructions or examples of the expected input, improving the user experience and reducing errors. 

<form>
  <input type="text" name="username" placeholder="Enter your username">
  <input type="email" name="email" placeholder="Enter your email">
  <input type="password" name="password" placeholder="Enter your password">
  <button type="submit">Submit</button>
</form>
