TASK 3: Add interactive features
For this task, two types of interactive behavior need to be added. These interactive behaviors are demonstrated in the accompanying video.

In the internal stylesheet, add a ruleset with this selector: use a pseudoclass of hover on all div elements. Add a declaration of color: blue.
Add the following script element before the closing </body> tag. It is a link to a file containing JavaScript code. After this is added, the "Your Face" image will be immediately shown in the web page after the user uploads a file. The JavaScript code shows the selected image in the img element with id="preview" that you added in Task 1 under the file input.

Test both the interactive features.
