This is a bug in LyX 1.1.6fix1. When you export a lyx file to html (File|Export|Html) using latex2html it includes a line <LINK REL="STYLESHEET" HREF="name_of_document.css"> The problem is that you copy the file name_of_document.html from the tmp/lyx directory but do not copy the file name_of_document.css. Is it possible to check for this file and copy to the same directory that name_of_document.html when converting to html? -- José Miguel Espadero Guillermo GnuPG key : http://jespa.escet.urjc.es/jespa.gpg.txt
