I have the following problem.My styles are defined in a .css that VF uses for the (Apply Style) dropdown.I want to replace old styles with new ones and existing content using using these styles need updating.However, VF would wrap a new around an old style rather than replacing it.For example, I had this tag that refered to a style removed from the stylesheet -<p><span class="contentBoldItalic">contentbolditalic</span></p>When I select a new style, it wraps around the old one (when I want it replaced) - <p><span class="heading3"><span class="contentBoldItalic">contentbolditalic</span></span></p>I have tried to use the equivClass but it makes no difference.Any ideas?
