In what ways can browser-specific validation functions impact the implementation of REGEX patterns in HTML forms, and how can these functions be leveraged effectively?

Browser-specific validation functions can impact the implementation of REGEX patterns in HTML forms by potentially overriding or conflicting with the patterns set in the form. To leverage these functions effectively, it is important to ensure that the REGEX patterns are compatible with the browser's validation requirements. This can be achieved by testing the form in different browsers and adjusting the REGEX patterns as needed.

<form action="submit.php" method="post">
  <input type="text" name="email" pattern="[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}" required>
  <input type="submit" value="Submit">
</form>
