Based on your algorithm(User valida- tion), write a program that does the same thing using HTML, CSS, and JavaScript. Use the scoring guide below: Import CSS design using link tag. The login page should be presentable. Import JavaScript using script tag Write JSON object in your JS file containing the following account: Username: john, Password: smith Username: mary, Password: woods Username: steve, Password: jobs •The program should be able to count the num- ber of login attempts. If it reaches the maximum threshold of 3 incorrect credentials, it should dis- able the login button. If the user was able to login with correct credentials(username and its corresponding password), use an alert to display ”successfully logged in!”. The program should be able to determine what goes wrong, for example, the ”user does not ex- ist” only appears when the username does not match to the accounts inside the JSON, and ”Incorrect password” if the username is correct but the password for that username is incorrect.
