Age Tester Problem in JavaScript

Objective:

Create a simple age tester application that checks whether a user is an adult or a minor based on their inputted age. The project will involve using HTML for the structure, CSS for styling, and JavaScript to handle the age-checking logic.

Project Requirements:

HTML Structure:
- Create an input field where the user can enter their age.
- Add a button labeled "Check Age" to submit the entered age.
- Include a display area (e.g., a paragraph or div) to show the result message.
CSS Styling:
- Style the application using basic CSS to ensure a clean and user-friendly design.
- Make the input and button clearly visible and aesthetically pleasing.
JavaScript Functionality:
- Capture the user's input when they click the "Check Age" button.
- Validate the input to ensure it’s a number and is within a reasonable range (e.g., between 0 and 120).
- Use an if-else statement to determine if the user is a minor (under 18) or an adult (18 and above).
- Display an appropriate message such as "You are a minor" or "You are an adult" in the result area.

Bonus Features (Optional):

Error Handling: Show an error message if the input is not a valid number.
Reset Button: Add a button to clear the input and reset the result display.
Additional Age Categories: Extend the logic to include more categories (e.g., senior for 65 and above).
