Age Tracker per 3h5a9

Age Tracker allows users to track their precise age in years, months, days, hours, minutes, and seconds based on their birth date. It also provides customization options to personalize the page's background, either by selecting a color or uploading an image.
Features:

• Age Tracker: Calculates and displays the user's age in real time, updating every second based on the provided birth date.
• Background Customization:
  • Choose a solid background color or upload an image.
  • Toggle between color and image backgrounds.
  • The selected background persists across sessions.
• Persistent Settings: All settings (birthdate, background color, and image) are saved in localStorage so they persist even when the page is reloaded or reopened in a new tab.
• File Upload: Users can upload a background image, and the image name will be displayed next to the file input for easy reference.

How it works:

1. Enter your birth date to start the age counter.
2. Customize the page background by either selecting a color or uploading an image.
3. Your settings (including background and birth date) are automatically saved and will persist on page reload or reopening.
