Having all one single line with black background and text in white

Question

I want to have one line of text with black background and the text in white. The line is alone and so it can be one paragraph.

I would like the coloration for the full width of the line and not only for the text.

The solution must work inside one minipage.

Is the line going to be a separate paragraph, or do you want to colour a single line in a larger paragraph? — Jake, Dec 08 '11 at 12:06

You can use a combination of \colorbox:

\documentclass{article}
\usepackage{xcolor}
\usepackage{showframe}
\usepackage{adjustbox}


\newcommand*\mylineI[1]{%
\par\noindent
\colorbox{black}{\makebox[\dimexpr\linewidth-2\fboxsep\relax][l]{\strut\color{white}#1}}%
\par}

\newcommand*\mylineII[1]{%
  \par\noindent\adjustbox{bgcolor=black,innercode={\color{white}}{},}%
                     {\makebox[\linewidth][l]{\strut #1}}%
  \par%
}
\begin{document}
\mylineI{Text Text Text Text}

\mylineII{Text Text Text Text}

\end{document}
\myline{Text Text Text Text}
\end{document}

EDIT: The second command uses the package adjustbox. So you have some extra options.

Of course the code can be extended width extra spacing and \xspace.

Thanks but this coloration is only for the text and not for the whole line... I've updated my question. – projetmbc Dec 08 '11 at 12:16

@projetmbc: I edited my answer and now using makebox. – Marco Daniel Dec 08 '11 at 12:25

Is there a way to minimize the spacing before the text ? – projetmbc Dec 08 '11 at 12:30
@projetmbc: Do you mean the space inside the black line? I used \par to create a new line. You can manipulate this. – Marco Daniel Dec 08 '11 at 12:36
Your second command looks better for my purpose. That's great ! – projetmbc Dec 08 '11 at 13:17

How about this?

\colorbox{black}{%
\begin{minipage}[b]{\dimexpr\textwidth-2\fboxsep\relax}
\strut\color{white}hello
\end{minipage}%
}

enter image description here

A new environment to do the equivalent is

\setlength\fboxsep{0pt}
\makeatletter\newenvironment{blackbox}
    {\noindent\begin{lrbox}{\@tempboxa}\begin{minipage}[b]{\dimexpr\textwidth-2\fboxsep\relax}\strut\color{white}}
    {\end{minipage}\end{lrbox}\colorbox{black}{\usebox{\@tempboxa}}}
\makeatother

which will give the same result with

\begin{blackbox}
hello
\end{blackbox}

Note that this leads to an overfull box if unless \setlength\fboxsep{0pt} is used before it. With that, the output looks like

Sorry, I've forgotten to indicate that I'll use this formatting in one minipage... – projetmbc Dec 08 '11 at 12:31
@MarkS.Everitt: You forgot some % and width \textwidth you created an overfull box. You must substrate the \fboxsep of \colorbox. – Marco Daniel Dec 08 '11 at 12:37
@MarkS.Everitt: Please see my answer (\dimexpr). Your second code uses a savebox. So you allows breaks. – Marco Daniel Dec 08 '11 at 12:55

@MarkS.Everitt: Why sorry.? You provided an alternative and tex stackexchange is a collection of solutions ;-) – Marco Daniel Dec 08 '11 at 13:02
I'll leave it in that case, with a disclaimer that it leads to an overfull box. :) – qubyte Dec 08 '11 at 13:04
@MarkS.Everitt: I edited you answer. Now you have no overfull boxes. – Marco Daniel Dec 08 '11 at 13:30
@MarcoDaniel: Thanks for the edit. I understand now. That's a neat way of reducing the box size to fit! – qubyte Dec 08 '11 at 13:33
