Has anyone worked on including some means for creating dockable headers, footers, and sidebars in HTML or CSS? A dockable header, footer, and sidebar would be helpful for HTML accessibility and backward compatibility. This can be visually accomplished with frames, currently. Frames, however, offer no backward compatibility, or, forward compatibility with a host of specialized user agents. (i.e. Frames work when you can see them, but not when you can't. The NOFRAMES element is not a suitable alternative as it requires tons of code duplication.) A dockable portion of text could solve the compatibility problem and eliminate the need for frames in most cases, as for most implementations of frames, to date, have been used for navigation aids. As far as implementing this in a new graphical user agent, it could simply map the docked elements to a framed display. Framed or segmented displays can be very useful, but, frames don't work well. The docked blocks should probably wrap if they are crowded for space. For example: Two left aligned, docked blocks with 50% height would be one above the other. Two left aligned, docked blocks with 100% height would be side by side. Another thought, the dockable portions should probably not allow for included HTML from a file. This requires some code duplication, but, we would be fighting the backward compatible and non-accessible problem of current frames. I have included two examples, one HTML and one CSS. It would probably be better implemented in CSS using the DIV element for block selection. Either way, here is a bit of code that I hope will demonstrate my thought. I have omitted unneeded information, only docking is in detail. -Sample HTML docking- <HTML> <BODY> <DOCK ALIGN="LEFT" TITLE="Navigation Bar" Width="10%" HEIGHT="100%"> <H2>Other Pages</H2> <P> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> </P> </DOCK> <DOCK ALIGN="TOP" TITLE="Where am I, and, how do get somewhere else?" Height="1%" WIDTH="100%"> <H1>Some really great web</H1> <P><A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A></P> </DOCK> <P> This text is not docked. It is located to the bottom and right of the docked text. It is free to go where it wants.</P> </BODY> </HTML> - Sample CSS Docking - <HTML> <HEAD> <STYLE> DIV.DOCKLEFT {DOCK: LEFT 10% 100%;} DIV.DOCKTOP {DOCK: TOP 100% 1%;} </STYLE> </HEAD> <BODY> <DIV CLASS="DOCKLEFT" TITLE="Navigation Bar"> <H2>Other Pages</H2> <P> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> <A>Some Link</A> </P> </DIV> <DIV CLASS="DOCKTOP" TITLE="Where am I, and, how do get somewhere else?"> <H1>Some really great web</H1> <P><A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A> | <A>Some Link</A></P> </DIV> <P>This text is not docked. It is located to the bottom and right of the docked text. It is free to go where it wants.</P> </BODY> </HTML> -End sample- ,David Norris World Wide Web - http://www.geocities.com/CapeCanaveral/Lab/1652/ My Home's Web - http://kg9ae.dyn.ml.org/ ICQ Universal Internet Number - 412039 E-Mail - kg9ae@geocities.com
