6.1 The document must have a paragraph of at least 10 lines of text that describe you. This paragraph must be centered on the page and have space for 20 characters per line only. A light-gray image of yourself must be superimposed over the center of the text as a nested element.

6.2 Modify the document described in Exercise 6.1 to add four buttons labeled, respectively, Northwest, Northeast, Southwest, and Southeast. When theyre pressed, the buttons must move your image to the specified corner of the text. Initially, your image must appear in the northwest (upperleft) corner of the text.

6.3 Modify the document described in Exercise 6.2 to make the buttons toggle their respective copies of your image on and off so that, at any time, the document may include none, one, two, three, or four copies of your image. The initial document should have no images shown.

6.4 The document must have a paragraph of text that describes your home. Choose at least three different phrases (three to six words each) of this paragraph, and make them change font, font style, color, and font size when the mouse cursor is placed over them. Each of the different phrases must change to a different font, font style, color, and font size.

6.5 The document must display an image and three buttons. The buttons should be labeled simply 1, 2, and 3. When pressed, each button should change the content of the image to that of a different image.
