Different headers/borders for each page

Question

I'd like to apply a different heading/border for each page. The footers will all be the same. I want it to look like this:

I can make the first two pages different but I don't know how to get subsequent pages to be different.

My code for the first two pages:

\documentclass[11pt]{article}

\usepackage[hmargin=1cm,bmargin=2cm,tmargin=2cm,centering]{geometry}
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage[rgb]{xcolor}
\usepackage{framed}
\usepackage{multicol}
\usepackage{lipsum}
\usepackage[none]{hyphenat}
\usepackage{parskip}

\definecolor{boxgray}{rgb}{.55,.54,.54}
\definecolor{bluey}{RGB}{0,121,194} %Alcon color
\definecolor{card}{RGB}{133,23,24}

\usepackage{tikz}
\usepackage{tikzpagenodes}
\usepackage{atbegshi}

\newcommand\Header{%
  \begin{tikzpicture}[remember picture,overlay]

      ([yshift=-2.5cm]current page.north west|-current page text area.north west) -- cycle;
  \node[font=\bfseries\color{white},anchor=east,

  {\fontsize{20}{60}\selectfont Text};
\end{tikzpicture}%
}

\pagestyle{empty}
\AtBeginShipout{\HeaderTwo\Footer}
\AtBeginShipoutFirst{\Header\Footer}


\begin{document}
\vspace*{2.cm}
%Page1leftbox
\begin{minipage}[t]{60mm}

    \begin{minipage}[t]{.95\linewidth}

        \lipsum[1-4]
    \end{minipage}
    \clearpage

and the code for the border for page 3:

\pagestyle{empty}
\AtBeginShipoutFirst{\Header\Footer}

\begin{document}
    \begin{minipage}[t]{.65\linewidth}
        \vspace{10pt}
        \begin{multicols}{2}
            \lipsum[1-6]
        \end{multicols}
    \end{minipage}
\end{document}

• How can I combine them all in to one document with the potential for more pages with different designs?
• This code seems to generate a blank page at the end of the document. Why? and how do I stop that?

Answer 1

One possibility using the background package:

\documentclass{article}
\usepackage[a6paper]{geometry}% just for the example
\usepackage{ifthen}
\usepackage[
  scale=1,
  opacity=1,
  angle=0
]{background}

% command for modular arithmetic
\def\truncdiv#1#2{((#1-(#2-1)/2)/#2)}
\def\moduloop#1#2{(#1-\truncdiv{#1}{#2}*#2)}
\def\modulo#1#2{\number\numexpr\moduloop{#1}{#2}\relax}

% definitions of colors to be used
\definecolor{color1}{RGB}{11,64,176}% blue
\definecolor{color2}{RGB}{133,23,24}% red
\definecolor{color3}{RGB}{107,107,107}% red

% command for the footer
\newcommand\Footer{%
\begin{tikzpicture}[remember picture,overlay]
\fill[color1]
  ([yshift=20pt]current page.south west)
    rectangle
  (current page.south east);
\end{tikzpicture}%
}

% header for pages congrunent with 3 modulo 0
\newcommand\Headerz{%
\begin{tikzpicture}[remember picture,overlay]
\fill[color2]
  (current page.north west) --
  (current page.north east) --
  (current page.east) --
  ([xshift=-50pt,yshift=-25pt]current page.north east) --
  ([yshift=-25pt]current page.north west) --
  cycle;
\fill[color3]
  (current page.east) --
  ([xshift=-50pt,yshift=20pt]current page.south east) --
  ([yshift=20pt]current page.south east) --
  cycle;    
\end{tikzpicture}%
}

% header for pages congrunent with 3 modulo 1
\newcommand\Headero{%
\begin{tikzpicture}[remember picture,overlay]
\fill[color2]
  (current page.north west) --
  (current page.north east) --
  ([yshift=-70pt]current page.north east)
      to[out=160,in=20]
  ([yshift=-70pt]current page.north west) --
  cycle;
\end{tikzpicture}%
}

% header for pages congrunent with 3 modulo 2
\newcommand\Headert{%
\begin{tikzpicture}[remember picture,overlay]
\fill[color2]
  (current page.north west)
     rectangle
  ([yshift=-25pt]current page.north east);
\end{tikzpicture}%
}

% include common footer
\backgroundsetup{contents=\Footer}

% add header depending on the value of the page modulo 3
\AddEverypageHook{%
  \ifthenelse{\modulo{\value{page}}{3}=0}
    {\backgroundsetup{contents={\Headerz}}}
    {%
      \ifthenelse{\modulo{\value{page}}{3}=1}
        {\backgroundsetup{contents={\Headero}}}
        {%
          \ifthenelse{\modulo{\value{page}}{3}=2}
            {\backgroundsetup{contents={\Headert}}}
            {}
        }%
    }
  \BgMaterial
}

The idea is to define as many different decorations you want for the headers and then to include them conditionally depending on modular arithmetic for the page counter; schematically

if the residue of the page number modulo 3 is zero 
    use \Headerz as background
else if the residue of the page number modulo 3 is one
    use \Headero as background
else if the residue of the page number modulo 3 is two
    use \Headert as background
fififi

Obviously this easily generalizes to an arbitrary number of different headers.

Here's a version using the decorations from the code in the question:

\documentclass{article}
\usepackage[
  hmargin=1cm,
  bmargin=2cm,
  tmargin=2cm,
  centering

  scale=1,
  opacity=1,
  angle=0,
  contents={}
]{background}

% command for modular arithmetic
\def\truncdiv#1#2{((#1-(#2-1)/2)/#2)}
\def\moduloop#1#2{(#1-\truncdiv{#1}{#2}*#2)}
\def\modulo#1#2{\number\numexpr\moduloop{#1}{#2}\relax}

% definitions of colors to be used
\definecolor{boxgray}{rgb}{.55,.54,.54}
\definecolor{bluey}{RGB}{0,121,194} %Alcon color
\definecolor{card}{RGB}{133,23,24}

% command for the footer

To do the conditional tests I borrowed the \modulo macro defined by egreg in his answer to How do I calculate n modulo 3 in LaTeX?.

If the backgrounds are not supposed to cycle through the pages, but every page must have its own decoration, you need to define as many decorations as pages in the document and then the code simplifies since a simple conditional test depending on the value of the page counter decides the background: A simple example with four backgrounds (I designed a quick decoration \HeadeFour for the fourth page):

The \clearpage commands in my example are just for brevity's sake (to quickly produce several pages); they are not really needed in a real document with real content.
