Her favorites are the Japanese logic puzzles that have become very popular in recent years.

Create the table body row group containing nine table rows with the first cell in each row containing a table heading cell displaying the letters A through I. 7. After the initial table heading cell in the first, fourth, and seventh rows, insert three table data cells spanning three rows and three columns each. Altogether, these nine data cells will store the nine 3x3 boxes that are part of the Sudoku puzzle. 8. In the first row of the table body, put the three table data cells in the greenBox, goldBox, and greenBox classes, respectively. In the fourth row, the three data cells belong to the goldBox, greenBox, and goldBox classes. In the seventh row, the three data cells belong to the greenBox, goldBox, and greenBox classes. 9. Go to each of the nine table data cells you created in the last two steps. Within each data cell, insert a nested table belonging to the subTable class. Within each nested table, insert three rows and three columns of data cells. Enter the digits from Figure 5-54 in the appropriate table cells. Where there is no digit, leave the table cell empty 10. Save your changes to the file, and then go to the stable.css style sheet in your text editor. 11. Create a style rule to collapse the borders of the spuzzle and subTable tables. 12. Add a 5-pixel outset gray border to the table data cells within the spuzzle table. 13. Set the font size of table header cells within the spuzzle table to 8 pixels and the font color to gray. 14. Set the height of table header cells within the table body row group of the spuzzle table to 40 pixels. 15. For table data cells within the subTable table, add the following styles: a) set the font size to 20 pixels and the font color to blue; b) set the width and height to 40 pixels and center the cell text both horizontally and vertically, and c) add a 1-pixel solid black border around the cell. 16. for table data cells nested within the goldBox class of table data cells, display the background image file gold.jpg centered within the cell and not tiled. (Hint: Use background position values of 50% for both the horizontal and vertical directions.) 17. For table data cells nested within the greenBox class of data cells, set the back- ground image to the green.jpg file, once again centered within the cell without tiling. 18. Add descriptive comments throughout your style sheet to document your work. 19. Save your changes to the file and then reload sudoku.htm in your web browser. Verify that the layout and design of the Sudoku table resemble that shown in Figure 5-54 20. Submit your completed files to your instructor, in either printed or electronic form, as requested.
