Hi Hans, hi guys,

thanks for your answer, but, at least in my ConTeXt installation, it  
does not affect the width of the textbackground (see example 1).

I also tried other approaches to set the width of a textbackground  
being larger than the actual text width. So far I solved it using  
\startnarrower.

However when a page break happens within the textbackground ConTeXt  
does not set it properly. The dimensions of the defined textbackground  
are correct. however you will see the color of the background only at  
the first page but not after the page break. below an example (example  
2).

Similar happens when I have double sided pages.

do you have an idea how to fix this issue?

Thanks!

Armin

********** EXAMPLE 1

\definetextbackground[zhu]
        [location=paragraph,
         background=color,backgroundcolor=orange,
         %frame=off,topframe=on,
         leftoffset=0.5\bodyfontsize,rightoffset=.5\bodyfontsize,
         topoffset=.5\bodyfontsize,bottomoffset=.5\bodyfontsize,
         before={\startnarrower[left,right]},
         after={\stopnarrower},
         width=\paperwidth,
         frame=off]

\starttext

\dorecurse{1}{\input knuth\endgraf}
\startzhu
\dorecurse{2}{\input bryson\endgraf}
\stopzhu

\dorecurse{1}{\input knuth\endgraf}

\stoptext

*********** EXAMPLE 2

\setupnarrower[right=-1.0cm,left=-1.0cm]
\definetextbackground[zhu]
        [location=paragraph,
         background=color,backgroundcolor=orange,
         leftoffset=0.5\bodyfontsize,rightoffset=.5\bodyfontsize,
         topoffset=.5\bodyfontsize,bottomoffset=.5\bodyfontsize,
         before={\startnarrower[left,right]},
         after={\stopnarrower},
         frame=off]

\startsetups important:start
	\starttextbackground[zhu]
\stopsetups

\startsetups important:stop
     \endgraf
     \stoptextbackground
\stopsetups

\definestartstop
	[important]
   	[before=\setups{important:start},
    	after=\setups{important:stop}]

\starttext

\dorecurse{1}{\input knuth\endgraf}
\startimportant
\dorecurse{2}{\input bryson\endgraf}
\stopimportant

\dorecurse{1}{\input knuth\endgraf}

\startimportant
\dorecurse{3}{\input bryson\endgraf}
\stopimportant
\dorecurse{1}{\input knuth\endgraf}
\startimportant
\input bryson\endgraf
\stopimportant
\stoptext
