Use the placeholder attribute in HTML to display a hint describing the expected value of the element.
Example
You can try to run the following code to implement placeholder attribute −
<!DOCTYPE html> <html> <body> <h2>Login</h2> <form action = "/new.php"> <input type = "text" placeholder = "Student UserName" name = "name"/><br> <input type = "password" placeholder = "Password" name = "password"> <br><br> <input type = "submit" value = "Submit"> </form> </body> </html>
