{{todo|Add more examples of usage of textbackgrounds.}}
Pages, paragraphs, words can have a background: color or screenframe. (See, eventually, the ConTeXt creates these using [[manual:details.pdf| detailsMetaPost]] manual for further explanations.) == What if textbackground doesn't work? ==
== Example: multi-page backgrounded text ==
In the following example, we also reduce the textwidth and bodyfont size.

Occasionally,however, it is necessary and {{cmd|ul}} or {{cmd|underbar}} doesn’t do what you want. In thosecases using {{cmd|definetextbackground}} for the underlining may also be tried.
