I have the following MWE:

documentclass[]{standalone}

usepackage{tikz}

usetikzlibrary{positioning,fit,shapes.geometric,calc,backgrounds}

begin{document}

begin{tikzpicture}



% Headers        

node (header1) {large HeaderOne};

node[right=of header1] (header2) {large HeaderTwo};



% Text

node[below=of header1.west, anchor=west] (text1) {Short text};

node[below=of header2.west, anchor=west] (text2) {A long line of text. A long line of text. A long line of text. A long line of text.};



% Background

begin{pgfonlayer}{background}

node [fill=gray!20, draw=black, fit=(current bounding box.north west) (current bounding box.south east)] {};

end{pgfonlayer}



end{tikzpicture}

end{document}

which produces this:

However, in addition, I would like to create a rectangle as background for HeaderOne and HeaderTwo, which also spans the width of the entire picture, a bit like this (please ignore the bad painting around the text itself; it should be drawn on the background layer):

I have tried using 'background top' from the pgf manual in conjunction with 'background rectangle', but this does not look good when you want to have drawn a black line (border) around everything as well (the border does not fit the entire picture then).

Thanks.

Just add another fit node and do not forget inner sep=0pt.

documentclass[]{standalone}

usepackage{tikz}

usetikzlibrary{positioning,fit,shapes.geometric,calc,backgrounds}

begin{document}

begin{tikzpicture}[every node/.style={minimum height=5ex}]



% Headers        

node (header1) {large HeaderOne};

node[right=of header1] (header2) {large HeaderTwo};



% Text

node[below=0pt of header1.south west, anchor=north west] (text1) {Short text};

node[below=0pt of header2.south west, anchor=north west] (text2) {A long line of text. A long line of text. A long line of text. A long line of text.};



% Background

begin{pgfonlayer}{background}

node [fill=gray!20, draw=black, fit=(current bounding box.north west) (current bounding box.south east), inner sep=0pt] {};

node [fill=red, draw=black, fit=(header1)(header2)(current bounding box.north east), inner sep=0pt] {};

end{pgfonlayer}



end{tikzpicture}

end{document}

Why don't use a simple table for that?

documentclass[margin=3]{standalone}

usepackage{colortbl}

usepackage{xcolor}

begin{document}

renewcommand{arraystretch}{1.5}

begin{tabular}{ll}

    hline 

    rowcolor{red}large HeaderOne & large HeaderTwo\hline 

    rowcolor{gray!20} Short text & A long line of text. A long line of text. A long line of text. A long line of text.\

    hline

end{tabular}

end{document}

If you want to use this table inside a TikZ picture, simply place it inside a node.

documentclass[margin=3,tikz]{standalone}

usepackage{colortbl}

usepackage{xcolor}

begin{document}

tikznode{renewcommand{arraystretch}{1.5}%

begin{tabular}{ll}

    hline 

    rowcolor{red}large HeaderOne & large HeaderTwo\hline 

    rowcolor{gray!20} Short text & A long line of text. A long line of text. A long line of text. A long line of text.\

    hline

end{tabular}};

end{document}

With pure TikZ it is also not that complicated. No need of PGF layers. However, I don't recommend this way.

documentclass[margin=3,tikz]{standalone}

usetikzlibrary{positioning}

begin{document}

begin{tikzpicture}[node distance=0pt,inner sep=7pt]

node[text width=3cm,font=largecolor{white},fill=red] (header1) {HeaderOne};

node[text width=3cm,below=of header1,fill=gray!20] (text1) {Short text};

node[text width=13cm,font=largecolor{white},fill=red,right=-pgflinewidth of header1] (header2) {HeaderTwo};

node[text width=13cm,below=of header2,fill=gray!20] (text2) {A long line of text. A long line of text. A long line of text. A long line of text.};

draw (header1.north west) -- (header2.north east)

    (header1.south west) -- (header2.south east)

    (text1.south west) -- (text2.south east);

end{tikzpicture}

end{document}
