Day 3 - Three Usability Guidelines for Forms

Here's a few usability guidelines when creating forms:

 * Forms are generally vertical so form labels generally work best above the fields. Users fill forms from top to bottom and putting labels to the left of the form creates two columns.

 * The ideal search box is 27 characters wide according to studies done by web usability expert Jakob Nielsen.   

 * Provide inline validation in forms.  Validation messages are shown immediately after the user types in data to form fields.  Inline validation gives the user real time feedback as they fill in the fields.
