Add the ability to individually validate each input field

**Is your feature request related to a problem? Please describe.**
Input fields should be able to be validated on an individual basis by the developer. Browser validation isn't always enough.

**Describe the solution you'd like**
add a boolean validated property to all inputs.

Acceptance criteria:
- all input types should have a boolean validated prop that gets set to true/false when valid/invalid
- should apply styles to inputs based on validated prop
