Does anyone run Emacs/w3 ?

Does anyone run Emacs/w3 ?

[Steven Woody]

I'm running Emacs/w3.  My Emacs was set as black background, this make
most pages look ugly.  Has any made a decent configuration for w3
running in this situation?

And, I found in w3, most pages do not wrap its long lines properly.  Is
this a bug? How do I resolv it?

Thanks in advance.

So am I.

For the rest of your question, I'm afraid you'd have to be more
specific if you really want useful answers.
W3 is far from perfect for me too. I use it mostly for pages I have
written myself. For the big world, I use Mozilla nowadays.

I'm  using this ugly  hook. It  started with  only removing  font size
tags, but as you can see, I added a number of ad-hoc pre-processing of
the html buffers.

A more general and stronger filter could be implemented in this hook.

Or you may use an online filter such as:

I run emacs/gnus in black background too:

Some code I snagged on gnus `ding' a few years ago when w3 was the
preferred html rendering engine for gnus.  Not sure if it might be
helpfull.  I no longer use w3 for that.

You could tell w3 to always prefer the user's colors.

Maybe frobbing truncate-lines or truncate-partial-width-windows will
help.  But I haven't used w3 in ages now.
