# Does latex have the z-index property

May be this is a very strange question. But I found this property is very useful to control the overlap element.

So I wonder if latex own this property as HTML div.

Do you have any better idea to solve the overlap problem. Sometime, I need to push some element back.

update:the MWE code



\documentclass{article}

\usepackage{listings}
\usepackage{courier}
\usepackage{caption}
\usepackage{xcolor}
\usepackage{calc}

\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\parbox{\textwidth}{\colorbox{gray}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,
labelfont=white,
textfont=white,
singlelinecheck=false,
margin=0pt,
font={bf,footnotesize}
}

\newlength\tdima
\setlength\tdima{ \fboxsep+\fboxrule}

\lstset{
basicstyle=\small\tt,
tabsize=2,
extendedchars=true,
breaklines=true,
mathescape,
escapeinside={\%*}{*)},
showspaces=false,
showtabs=false,
showstringspaces=false,
columns=flexible,
xleftmargin=\tdima,
framextopmargin= 10pt,
framexbottommargin=10pt,
float=tp,                            % float setting
frame=single,
}%

\begin{document}
\begin{lstlisting}[caption=overlap]
using namespace std;
int main(void)
{
return 0;
}
\end{lstlisting}
\end{document}



Output:

The caption overlap with the frame. And I want to push the caption back. Let the frame cover it. I don't want to use the \vskip to fine tuning the caption position.

Please give a minimal working example (MWE) where you want to control such an overlapping. –  canaaerus Jun 22 '12 at 18:09
@canaaerus please take a look at the revised edition question –  pythonee Jun 23 '12 at 7:21
I guess adding another \colorbox with a white background around the code should be the way to go, although I don't know how to achieve this with lstlisting. (As you can see the border is already in front of the label.) Maybe just adding backgroundcolor=\color{white} will do it. –  canaaerus Jun 23 '12 at 7:22

Add a dimension to \fboxsep, as follows:
  \DeclareCaptionFormat{listing}{\fboxsep=1.2pt....
