Re: emacspeak and w3

["Robert D. Crawford" <robdcraw@xxxxxxxxxxx>]

I think I have the set-up you are looking for.  I have the following
variables that seem to be pertinent:

'(w3-default-stylesheet "~/.w3/default.css")
'(w3-honor-stylesheets nil)
'(w3-user-colors-take-precedence t)
'(w3-user-fonts-take-precedence t)

I have also attached my default.css file.  I have a black background
with the paragraph text in white.  Since we are both in the same boat as
concerns vision, I think this will work for you... that is unless
something else is in the way.

Best regards,
rdc

**       File: default.css
**    Purpose: Default Stylesheet for Emacs/W3
**       Info: Copyright (c) 1995-1996 William M. Perry <wmperry@xxxxxxxxxxx>
**             Copyright (c) 1997 Free Software Foundation, Inc.
**    Created: William M. Perry <wmperry@xxxxxxxxxxx>, Aug-31-1995
** Maintainer: William M. Perry <wmperry@xxxxxxxxxxx>
**
**  This contains the top level fallback default styles for Emacs/W3
**
*******************************************************************************
**
** To specify device-dependent styles, you must mark a section with
** @media devicetype { ... }
** If you are not using 'devicetype', then anything within the { ... }
** is ignored.
**
** These sections are currently defined by
** http://www.w3.org/pub/WWW/Style/Group/WD-PRINT-961220
** 
**    print  - output for paged opaque material, and for documents viewed
**             on screen in print preview mode
**    screen - a continuous presentation of computer screens
** projector - paged presentation for projected presentations
**   braille - for braille tactile feedback devices
**    speech - aural presentation
**       all - the default value, applies to all output devices
**
** There are a few special Emacs/W3 sections
**
**     emacs - only include this chunk if you are using Emacs 19
**    xemacs - only include this chunk if you are using XEmacs
** multifont - only include this chunk if you are using a multi-font capable Emacs variant
**   unifont - only include this chunk if you are using a uni-font capable Emacs variant
**     light - only include this chunk if you are using a light background
**      dark - only include this chunk if you are using a dark background
**       tty - only include this chunk if you are using a TTY
**  ansi-tty - only include this chunk if you are using an ANSI-capable TTY 
*******************************************************************************
**
** There are some things this stylesheet cannot really specify, that we 
** must rely on the browser to explicitly handle correctly:
**
** o table formatting
** o actually creating a hyperlink from an <a> tag and its attributes
** o specifying which tags open lists
** o inlined images
** o frames (perhaps with positioning)
** o applet/script/embed/object
** o horizontal rules

>>>> Â Â>>> running and put the diffs in a w3-patches directory
>>>> Â Â>>> within the emacspeak distribution. This would make it

>>>> Â Â>>> patches you have been using. In addition to making it
>>>> Â Â>>> easier for users, it may help in tracking down problems
>>>> Â Â>>> as we will have a common base everyone is working from.
