How can I add horizontal line after header and before footer?

header

---------



---------

footer

Your easiest approach here would be to include the fancyhdr package and set the header/footer rule widths using renewcommand:

documentclass{article}

usepackage{fancyhdr}% http://ctan.org/pkg/fancyhdr

pagestyle{fancy}% Change page style to fancy

fancyhf{}% Clear header/footer

fancyhead[C]{Header}

fancyfoot[C]{Footer}% fancyfoot[R]{thepage}

renewcommand{headrulewidth}{0.4pt}% Default headrulewidth is 0.4pt

renewcommand{footrulewidth}{0.4pt}% Default footrulewidth is 0pt

begin{document}

Here is some text.

end{document}

Headers and footers are simultaneously cleared using fancyhf{}, and individually set using fancyhead[<pos>]{<stuff>} and fancyfoot[<pos>]{<stuff>}. See the fancyhdr documentation.

Modifying the colour of the header/footer rules is a bit more tricky, since fancyhdr doesn't supply this modification by default. etoolbox can be used to update the two rule macros headrule and footrule to insert the colour as needed. They are defined as follows:

defheadrule{{if@fancyplainletheadrulewidthplainheadrulewidthfi

    hrule@heightheadrulewidth@widthheadwidth vskip-headrulewidth}}



deffootrule{{if@fancyplainletfootrulewidthplainfootrulewidthfi

    vskip-footruleskipvskip-footrulewidth

    hrule@widthheadwidth@heightfootrulewidthvskipfootruleskip}}

It is clear that the horizontal rule is drawn using hrule, so we can patch these commands and insert color{<colour>} just before drawing it by means of the following convenient helper macros:

usepackage{etoolbox,fancyhdr,xcolor}% http://ctan.org/pkg/{etoolbox,fancyhdr,xcolor}

% patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}

newcommand{headrulecolor}[1]{patchcmd{headrule}{hrule}{color{#1}hrule}{}{}}

newcommand{footrulecolor}[1]{patchcmd{footrule}{hrule}{color{#1}hrule}{}{}}

This allows you to use headrulecolor{<colour>} or footrulecolor{<colour>} in order to change them individually. The above patch is standard for etoolbox, so see the etoolbox documentation on how patchcmd works. Here's a complete MWE:

documentclass{article}

usepackage{etoolbox,fancyhdr,xcolor}% http://ctan.org/pkg/{etoolbox,fancyhdr,xcolor}

% patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}

newcommand{headrulecolor}[1]{patchcmd{headrule}{hrule}{color{#1}hrule}{}{}}

newcommand{footrulecolor}[1]{patchcmd{footrule}{hrule}{color{#1}hrule}{}{}}

pagestyle{fancy}

fancyhf{}% Clear header/footer

fancyhead[C]{Header}

fancyfoot[C]{Footer}% fancyfoot[R]{thepage}

renewcommand{headrulewidth}{0.4pt}% Default headrulewidth is 0.4pt

renewcommand{footrulewidth}{0.4pt}% Default footrulewidth is 0pt

headrulecolor{red!70}% Set header rule colour to 70% red.

end{document}

Here's another option using the titleps package:

documentclass{article}

usepackage{titleps}



newpagestyle{ruled}

{sethead{}{Header}{}headrule

  setfoot{}{Footer}{}footrule}

pagestyle{ruled}



begin{document}

Here is some text.

end{document}

Redefining makeheadrule and makefootrule, you can change the attributes; for example, to change the color:

documentclass{article}

usepackage{xcolor}

usepackage{titleps}



newpagestyle{ruled}

{sethead{}{Header}{}headrule

  setfoot{}{Footer}{}footrule}

pagestyle{ruled}



renewcommandmakeheadrule{color{cyan}rule[-.3baselineskip]{linewidth}{0.4pt}}

renewcommandmakefootrule{color{cyan}rule[baselineskip]{linewidth}{0.4pt}}



begin{document}

Here is some text.

end{document}

Of course, you can switch to other page style at any moment:

documentclass{article}

usepackage{titleps}



newpagestyle{ruled}

{sethead{}{Header}{}headrule

  setfoot{}{Footer}{}footrule}

pagestyle{ruled}



begin{document}
