Do use only approved images of the BaBar elephant to avoid copyright infringements. Don't keep Babar related web pages in your home directory. Don't use frames. Frames present a security risk . Frames prevent search engines from finding information.
Frames diminish the ability to print a screen's worth of data.
Consequently, each frame must be selected and printed individually. By default, typically, unvisited links are blue and visited links are red. Users often take advantage of knowing which colors their browsers use for followed and unfollowed links. Don't use light text on a dark background. This is difficult to print and often unpleasant to read.
