A simple login form is a user interface component typically found on websites or applications that require user authentication. It consists of input fields for the user to enter their credentials usually a username or email and a password and there should be a submit button to initiate the login process.
How to create a simple login form
here are the steps:
- Create a new folder for your project and inside the folder create two fields, those are:’index.html’ and ‘styles.css’.
- Open the file ‘index.html’ and create the basic structure of an HTML document.
- Inside the ‘<body>’ tag, create a ‘<form>’ element to hold your login form.
- Inside the ‘<form>’ elements, add ‘<input>’ elements for username and password. Use the ‘type’ attribute to specify the input type “text” for username and “password” for password.
- Add ‘<label>’ elements for each input field to provide a discription .
- Add a ‘<button>’ element inside a form to act as a submit button.
- Open ‘style.css’ and add CSS rules to style the login form.
- Open ‘index.html’ which is on desktop in a web browser and test your login form.

Email id validation using JavaScript
Validating email addresses using JavaScript involves checking if the input provided by the user matches a certain pattern that conforms to the standard format of an email address.
here are the steps:
- Create an HTML file where form elements are defined for the email address and displaying error messages.
- Define JavaScript functions to handle form submission and validate the email address entered by the user.
- Attach event listeners to the form elements for validation when the form is submitted.
- show error messages if the email address entered by the user is invalid
