Body Styles Go to the pc_specials.css file and within the Page Body Styles section, add a style rule for the body element that sets the width of the page body to 95% of the browser window width within the range 640 pixels to 960 pixels. Horizontally center the page body within the window by setting the left and right margins to auto . Image Styles Go to the Image Styles section and create a style rule that displays all img elements as blocks with a width of 100%. Navigation List Styles Anne wants the navigation list to be displayed horizontally on the page. Go to the Horizontal Navigation Styles section and create a style rule for every list item within a horizontal navigation list that displays the list item as a block floated on the left margin with a width of 16.66%. Display every hypertext link nested within a navigation list item as a block. Row Styles Next, you'll create the style rules for the grid section of the March Specials page. Go to the Row Styles section. For every div element of the newRow class, create a style rule that displays the element with a width of 100% and only when all floated elements have been cleared. Using the technique from this tutorial, add another style rule that uses the after pseudo-element to expand each newRow class of the div element around its floating columns.
