More decoration for babel output

More decoration for babel output

[Ken Williams]

[-- Attachment #1: Type: text/plain, Size: 884 bytes --]

Hi all,

When exporting to HTML I always add some extra CSS to my org-mode config, for the purpose of identifying which chunks are input vs. output, and for identifying the language of the code in code chunks.  Language is identified by a little label on the box, and input/output is identified by green/red.

Would this be helpful to include by default?  Patch attached.

As for me, with slight adaptations, I am including it in my operating
systems class notes. Thanks!

This look fine -- can you send a screenshot?

I cannot apply the patch until you assign your copyright to the FSF.
Would be nice if you can do it!  Here is the form:

FWIW, the only changes I did to your css is to use darker backgrounds
(#336666 instead of #F5FFF5), as the code is hardwired to somewhat
inconvenient colors (some very dark, some very bright) and the result
was hard to read.

I committed something deeply inspired by your patch, 
but slightly different.  Please have a look (from master)
and let me know if you think this is okay.

Thanks for this idea!
