How Validation Works in Browsers

  • Browser’s Built-In Error Messages: If the input doesn’t match the pattern, the form won’t submit, and the browser displays an error message like “Please match the requested format.”
  • Custom Error Messages with title: Adding a title attribute lets you specify custom instructions, which are appended to the browser’s default error message for improved clarity.
