# Fancy Headers and final Footers in LaTeX

This post explains advanced uses of headers and footers. The template changes between two fancy pagestyles and provides a TikZ based header and a – alsoTikZ based – final footer which only appears on the very last page of the document (which LaTeX will determine on its own without you setting it explicitly).

[Markdown is kind of broken in this post. Parts of it were repaired but other parts seem stubbornly broken (and break over and over again), so I decided that it will be ok to stay like this. If you’re interested in the information – it’s all here. It doesn’t look so good but that you should be able to survive 😉 ]

This post is not intended for beginners who just want to make simple use of the basic fancyhdr features. A great explanation of these can be found in the ShareLaTeX tutorial (see “Resources” section below).

So if you don’t care to read the following (long) explanation of these advanced header / footer uses, just use my Overleaf template and come back here if you want to customize something to get information you need. All the facts are here.

You can find it here.  It’s a view-only share link to the template I created but I can’t publish it as a template via Overleafv2, so have fun with the link (hopefully this will be possible later). Just copy it as your own project or something.

The code can be found in full in the Overleaf template and has extensive comments. I will, however, explain all the snippets even more in detail in this post, so you can understand what I did and why I did it. Especially because the code to create this might be overwhelming to you in whole if you haven’t done a lot of advanced LaTeX customizing so far.

### General settings for our document

This is the preamble, not a lot to explain here so far, so just the code:

### Setting header and footer with the fancyhdr package

Why is this chapter here? Didn’t I say I was not going to do the basic fancyhdr explanation? Yes, I did indeed. This is why you’ll just get the code snippet with its comments from Overleaf. What I did here is no sorcery and can be understood from the ShareLaTeX tutorial (see “Resources” below). I find that ShareLaTex generally does a great job in explaining the stuff you really need, even as an advanced user. It gives an overview on the most common packages without being as confusing as their package documentations. Definitely worth checking! ( https://www.sharelatex.com/learn )

% Settings for "normal" headers and footers
%-------------------------------------------------------------------
\usepackage{fancyhdr} % http://mirror.easyname.at/ctan/macros/latex/contrib/fancyhdr/fancyhdr.pdf
\pagestyle{fancy}

\fancypagestyle{fancy1}{
\fancyhf{} % clear space at the header and footer so the fancy headers / footers can be placed
%-------------------------------------------------------------------
%\renewcommand{\footrulewidth}{1pt} % same would be possible if you wanted a footer rule
%-------------------------------------------------------------------

% things you might want to access here: \thesection \thechapter \chaptername \sectionmark \rightmark \leftmark
% check this for further info: https://en.wikibooks.org/wiki/LaTeX/Customizing_Page_Headers_and_Footers

% puts a small logo on the right side of the HEADER - same goes for the \lhead:
\lhead{\footnotesize\textbf{Example citation:} \textsc{Author-Lastname}, Surname: Article title'', in: \textsc{Editor} (ed.): \emph{booktitle}, NY 2018. {\textsc{Link:}} \protect\url{http://mylink.com}{ } \lbrack{}\today\rbrack{}.}
% you could you \chead to access the center as well

%-------------------------------------------------------------------
% defines all the FOOTER settings. But in this case, they are conditional: We check if we're on the last page and only print it, if we're not.
\rfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else\includegraphics[width=0.1\textwidth]{logo.jpg}\fi}
\lfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else{\scriptsize your custom footer text goes here}\fi}

% add the page count in the middle: \thepage gives you the current page, \pageref{LastPage} the total
\cfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else\thepage/\pageref{LastPage}\fi}
}

If the part where the if conditions turn up in the footer settings confuse you, don’t worry. I will explain this in the final footer part.

## Creating the final footer

### Using hooks to find the last page of a document

Finding the last page of a document in LaTeX is not as trivial as it might seem. Sometimes, you might succeed just using \AtEndDocument. But this will only work if the contents of the last page have not been shipped out before LaTeX realizes it needs to check if it’s the last page. Sometimes, this will work just fine. Other times, all the content is already printed once you reach this point. This is why we need the atveryend package which will help us find the real last page of our document by setting some more page hooks after the \AtEndDocument is executed and after the last shipout is done.

In our example, we trigger this behaviour in the fancyhdr part where we check if we’re on the last page. Then, we don’t want fancyhdr to print the footer. Because now, our footer background will executed: That’s right – our final footer is actually a TikZ-based background setting which is only applied to the last page where we disabled the fancyhdr footer.

Having used \usepackage[pages=some]{background}, we could also invoke this background manually anywhere we want like this: \BgThispage. This, however, I found a bit tedious. I wanted to automatically create LaTeX output from XML files using XSLT transformation. So, of course, I wouldn’t be able to manually add \BgThispage at every document’s last page. First of all, because it’s tedious and then, how do you even know where this is if you don’t typeset all the pagebreaks by hand? So I came up with the solution presented here.

(I am not 100% sure, however, if this is the most elegant or failsafe solution possible – always happy to get your feedback!)

\scriptsize\lipsum[56]
\end{minipage}
}{
\includegraphics[width=0.5\textwidth]{jack.jpg}
}{
\includegraphics[width=0.4\textwidth]{logo.jpg}
}

%-------------------------------------------------------------------
%--------------------------------------------------------------------------------- End footer placement
\usepackage{everypage}
% here we determine that the footer (which really is a background constisting of TikZ picture
%will be printed on the very last page only
%\AfterEndDocument{\clearpage\vfill\fancyhf{}\cfoot{}\rfoot{}\lfoot{}\BgThispage}

A possible problem with this solution might be that I never use \thispagestyle{empty}, so your content could possibly overflow into the footer, if the last page is very full. Usually it doesn’t do that and if it does, it can usually be avoided by rearranging the last few pages a little bit. When you don’t do automated transformations like I did, this shouldn’t bother you much. Also, with the geometry settings I used, I found that it wasn’t much of a problem and only a tiny bit visible when I, for example, excessively used footnotes on the last page.

If you want to absolutely ensure that your header and footer are cleared, you have to use  \thispagestyle{empty}, which will overwrite  \pagestyle{fancy} we set at the beginng, but for the current page only. Mind you though, this will not only affect the footer section but cause you to have no header as well. This is why I don’t do it and accept some minor overflow as the tradeoff.

\thispagestyle{plain} will remove the header and footer for one page but at least will keep the page numbering in the footer, by the way. Non-fancy, LaTeX automatically created centered page numbering, that is. So no “page 3 of 3”. Just “3”.

## The header using a TikZ background

The header command I created resembles the footer in the way that it is also a TikZ background, only this time it’s not set to be transparent (like above) and it’s at the top of the page. This time, I also want to be able to use this for every page I want, whenever I want. (We could configure it as a replacement / version of \maketitle which some people do in custom CV templates, but I prefer it this way. It keeps me in control of my document.) While the footer just has three textareas you can fill as you please, the header has one circle for a picture and three spots for text. It’s a header I configured for a CV template, so feel free to make your own version of this header command to fit your needs.

%-------------------------------------------------------------------
% inspired by: https://www.sharelatex.com/templates/cv-or-resume/fancy-cv
\tikz[remember picture,overlay] {%
\node[rectangle, fill=#5, anchor=north, minimum width=\paperwidth, minimum height=5cm](header) at (current page.north){};%
\node[anchor=south east](degree) at (name.north east) {\fontfamily{\sfdefault}\selectfont\flushright #1};%
\node[anchor=north east](descr) at (name.south east) {\fontfamily{\sfdefault}\selectfont #3};%
\draw[path picture={\node[anchor=center] at (path picture bounding box.center){\includegraphics[height=4.3cm]{#4}} ;}] (picture) circle (2) ;}%
\vspace{1.5cm}%
}
%-------------------------------------------------------------------

For this command to work, I had to ensure there was more than one fancy pagestyle available because we don’t want a normal header displayed when using this special one. Also, the special header needs some tweaking with geometry etc. because it’s larger and in the fancyhdr package, we have the problem that the footer will disappear when \headheight becomes too large. In our case, large means 5cm – that’s too large for fancyhdr.

So we set a new geometry locally for the page the header command is used on and restore it afterwards. We also activate the pagestyle for these pages only by using \thispagestyle{header} instead of \pagestyle{header}.

\usepackage{afterpage}

\fancyhf{} % clear space at the header and footer again
%-------------------------------------------------------------------

%-------------------------------------------------------------------
% defines all the FOOTER settings to work as above.
% We still check if we're on the last page and only print it, if we're not.
\rfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else\includegraphics[width=0.1\textwidth]{logo.jpg}\fi}
\lfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else{\scriptsize your custom footer text goes here}\fi}

% add the page count in the middle: \thepage gives you the current page, \pageref{LastPage} the total
\cfoot{\ifnum\getpagerefnumber{VeryLastPage}=\value{page}\else\thepage/\pageref{LastPage}\fi}
\afterpage{\restoregeometry}
}

\fontfamily{\sfdefault}\selectfont selects the raleway font we loaded in the preamble. This is just because I thought it looked good. Do whatever you want.

The command takes a background colour as one argument, the three textareas, the image location and two centimenter values for the placement of the image circle and the texts in the header. The first three arguments are the text areas.

By the way (did I mention this already?), this header command comes from a custom CV template I created. I will show it to you as soon as I’m fully happy with it. But so far, suffice it to say that it was inspired by the friggeri-cv class (as always, see “Resources” for links).

# Jumpstarting: Learn LaTeX in 3 minutes

Inspired by the learn x in y minutes tutorials, here comes my contribution to starting LaTeX quickly. If you want to jumpstart learning LaTeX, open your Overleaf account (or get one, they just require your email, no other info, takes 30 seconds) and open a blank or example project.

A blank project will give you the following output:

\documentclass{article}
\usepackage[utf8]{inputenc}

\title{\LaTeX in 3 min}
\date{January 2019}

\begin{document}
\maketitle

\section{Introduction}

\end{document}

You can now start typing text. Wherever you want, but for now, preferably below \section{Introduction} and in between \begin{document} and \end{document}.
The stuff before is the settings which don't interest you just yet. There you can see fields for title and author which \maketitle uses to make a title. This is what you can use to generate a title page later on.

Now type a sentence below \section{Introduction}, then hit space twice. Write another test sentence. Hit space twice and write \subsection{test}.

Now add \tableofcontents below \maketitle. Cool, huh?

\textit{makes text italic}, a similar but different effect is achieved with \emph{which highlights}. Make some \textbf{bold} statements and don't forget the quotes''\newpage will cause a manual pagebreak. Now copy this sentence into your test document.

Add \usepackage{hyperref} below the other \usepackage. Then add \href{http://latex-ninja.com}{\LaTeX{} Ninja} in the text.

With that, I think my 3 minutes are more than over and you are ready to go and do some exploring on your own.

Yours,

the LaTeX Ninja

PS: You might also be interested in the the Visual FAQ, a document showing things you might want to achieve with LaTeX which you can just click and it will redirect you to a TeX-FAQ tutorial where the chosen thing is explained. This is great if you want to get going as quickly as possible and learn as you go. Which you will have to or I won't keep my promise of an intro to LaTeX in 3 minutes 😉

PPS: The goal of this tutorial was not to give the illusion one could learn complete LaTeX in 3 minutes but rather to give you a quick "jumpstart" into LaTeX. In learning new things, people often don't try things out because the initial hurdle is too big. This post, on the opposite, is supposed to get you actively using LaTeX straightaway.
