# Building a User Registration and Login Form with Validation

Creating a registration and login page is a fundamental aspect of web development, particularly when user authentication is required. This article walks through the process of building a simple yet effective registration and login form using HTML, CSS, and JavaScript validation.

### HTML Structure
The HTML form structure for registration and login consists of two primary sections: one for user registration and the other for user login. Each section collects specific details from the user, such as name, email, phone number, and password.

In the registration form, users are prompted to enter their full name, email, phone number, password, and date of birth. This form is designed to validate the user's age and ensure they meet the minimum age requirement for registration.

For the login form, users provide their email and password to gain access.

Here's the breakdown of the HTML code used:

**Registration Form**
The registration form collects necessary user information, such as name, email, phone, password, and date of birth. It includes an input field for each item, with the password field for security.

**Login Form**
The login form only requires the user’s email and password to proceed. Once the user enters these details, they can access the application (assuming credentials are valid).

**CSS Styling**
CSS styling is applied to ensure the forms are visually appealing and easy to navigate. The background color of the page is a soft green, while the form itself has a white background with padding, making the input fields clear and easy to read. The forms are centered on the page, and button elements have consistent padding and color schemes to enhance the user experience.

The following CSS is used:

Background color of the page is light green to provide a refreshing feel.

Form container is given a maximum width and center-aligned to ensure it remains focused on the page.

Input fields and buttons are styled for easy interaction, with ample padding for usability.

**JavaScript Validation**
Age Validation
A key feature of the registration form is validating the user's age. The user’s date of birth is collected and used to calculate their age. If the user is under 18, they are alerted that they are not eligible for registration.

**Password Validation**
Another important validation step is ensuring that the password adheres to security standards. The password must:

* Be at least 8 characters long
* Contain at least one lowercase letter
* Contain at least one uppercase letter
* Contain at least one number

These rules are enforced using JavaScript, which checks the password entered by the user and alerts them if the password doesn't meet these conditions.

### Challenges
The challenge am currently facing is because am a total beginner of javascript trying to meetup up and make my web page more active and flexible.

### Conclusion
This simple registration and login form demonstrates the basic functionality of collecting user information, ensuring it meets certain criteria, and validating passwords for security.
