Form Refinements

[siqbal181]

Form is created at a very basic level but could do with some refinements such as:

• Edge cases for form inputs EG:
• User can't submit form without checking some boxes
• User inputs "other" fields without commas
• Anything else which ensures the user inputs the details exactly as we need

• changed checkboxes to radio for the mandatory age options
• changed for= to htmlFor= (The reason is that in JSX, for is a reserved keyword for "for loops." To avoid conflicts, JSX uses htmlFor to achieve the same behavior as the regular for attribute in HTML.)
