Background color for main text only

  • Follow


I need to set a background color in about 50 pages of my document, but
for the main text only. The footnotes should be set without this
background color.

Using the usual macros, I can set the background for an entire page or
document (which gives footnotes the same background), or enclose text
within boxes, frames, or minipages, which can mess up footnotes or the
page breaking algorithm.

I've tried playing with the output routines a bit, but perhaps someone
already has a solution. Any suggestions would be appreciated.

stupid idea: give entire page a color, then draw white box with and
below footnote line?

The following solution uses \pdfsavepos, provided by pdfTeX/LuaTeX 
(both DVI and PDF mode) and XeTeX. It redefines \@makecol to
get to the position of the footnote rule.
