Problem
1. Create a Web page that will prompt the user for a color name. Use this color name to write the text "This is your favorite color!". The fg Color property of the document changes the text color of all text in a document. Use this property to accomplish this task.
2. Extend Hands-On Practice 14.8. Add a text box for the user's city. Ensure that this text box is not empty when the form is submitted. If the city text box is empty, pop up an appropriate alert message and do not submit the form. If the city text box is not empty, and other data is valid, submit the form.
