{{todo|Add more examples of usage of textbackgrounds.}}
Pages, paragraphs, words can have a background: color or screen. Note that
"
screen
"
is
depricated
deprecated
in
MKIV
MkIV
.
(See, eventually, the [[manual:details.pdf| details]] manual for further explanations.)
== What if textbackground
doesn't
doesn’t
work? ==
The textbackground commands require [[write18]] to be enabled; see that page for more information.
In the following example, we also reduce the textwidth and bodyfont size.
<context source="yes">
\setupcolors[state=start]
\definetextbackground[secondary][
location=paragraph,

backgroundcolor=

lightgray
,
leftoffset=.5\bodyfontsize,
rightoffset=.5\bodyfontsize,
topoffset=.5\bodyfontsize,
bottomoffset=.5\bodyfontsize,

after={\stopnarrower},

,
]
\starttext
