All of the HTML report formats provided, except those derived from Microsoft Word, use a CSS1 stylesheet to specify font, color, size, and spacing details. Use of CSS1 allows these details to be separated from other aspects of page layout and placed into one or more re-usable stylesheets. Therefore, the easiest way to customize these aspects of the HTML reports is to edit the CSS files that they use. For further information about CSS1, refer to the W3C CSS1 specification, currently available at the following URL: http://www.w3.org/TR/REC-CSS1

Two CSS files are involved: htmlFormat4Print.css and htmlFormat4Screen.css. Both are located in <Windchill codebase>/templates/reports. The htmlFormat4Print.css file is intended to specify the appearance of HTML when printed and the htmlFormat4Screen.css file when viewed on screen. Actually, browsers do not support this aspect of CSS and, therefore, the printed output is controlled by htmlFormat4Screen.css as well. However, you may prefer htmlFormat4Print.css to htmlFormat4Screen.css, which is designed primarily for consistency with other Windchill HTML pages.

To change the CSS stylesheet used by a report or to make larger changes to the output format than possible through CSS1, you must customize XSLT stylesheets as described in the next section.
