Four style sheets affect the display characteristics of text in the product interface:
lockhart.css. Contains Sun corporate interface styles for web applications.
customStyle.css. Contains any changes to the default settings contained in style.css. and lockhart.css. Settings in this file override the settings in style.css and lockhart.css. Customers should not edit the preceding files, but instead put their customizations into customStyle.css.
Styles-Help.css. Defines style classes used in online help and pop-up help (i-Help).
