# Beamer,adjust separator in top/bottom lines

I would like to adjust the separators (to the left) in the top and bottom lines of beamer slide with Warsaw theme, so that there is more space to the right of separator. Is it possible?

Minimal working example:

    \documentclass[slidestop,compress,11pt]{beamer}
\mode<presentation> {
\usetheme{Warsaw}
}
\title[Test]{Test }
\begin{document}
\section{section1}
\subsection{subsection1}
\begin{frame}
\end{frame}
\subsection{subsection2}
\begin{frame}
\end{frame}
\end{document}

• Your code doesn't compile (at least not under pdfLaTeX). Please fix it. – Mico Oct 21 '16 at 18:13
• The should be <presentation> after \mode, but by some reason it doesn't show up. don't know how to fix it,sorry. – strider Oct 21 '16 at 18:23
• Removing the <code> and </code> tags did the trick, i.e., made <presentation> show up. :-) – Mico Oct 21 '16 at 18:28
• Can you please clarify what separator you are talking about and where the space shall be increased? Perhaps take a screenshot and mark the area? – user36296 Oct 21 '16 at 19:16
• separator between black and blue areas on the very top and very bottom lines (on slide from MWE code). On the top line it splits chapter's and section's names. I don't know how to post screenshots here yet. I will add a couple sections in a minute so that it become more clear. – strider Oct 21 '16 at 20:20

Normally the width of the beamercolorboxes is wd=.5\paperwidth for both sides. In the following example I shifted them to .3 and .7 [the width of the navigation element has to be changed in the same way]

\documentclass[slidestop,compress,11pt]{beamer}
\mode<presentation>{
\usetheme{Warsaw}
}
\title[Test]{Test}

\makeatletter
\leavevmode%
\end{beamercolorbox}%
\end{beamercolorbox}%
}

\setbeamertemplate{footline}{%
\leavevmode%
\hbox{\begin{beamercolorbox}[wd=.3\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm plus1fill,rightskip=.3cm]{author in head/foot}%
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.7\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}%
\end{beamercolorbox}}%
\vskip0pt%
}

\makeatother

\begin{document}
\section{section1}
\subsection{subsection1}
\begin{frame}
\end{frame}
\subsection{subsection2}
\begin{frame}
\end{frame}
\end{document}


• Yes, thats what I'm trying to do, thank you! This is much more code than I expected, and I don't understand 90% of it. Still fine if it doesn't interfere with the other code I have (still need to verify this). Could you please explain how does the above code works? Where can I find documentation about macros you used here? – strider Oct 21 '16 at 20:49
• which parameter affects the position of separator? – strider Oct 21 '16 at 20:55
• There is no parameter for the position, but in each bar are two boxes besides each other and you can manipulate their width by changing the three occurrences of wd=.3\paperwidth and the three ones of wd=.7\paperwidth [the sum should add to one in order to fill the whole page]. Documentation about the components can be found in the beamer user guide. – user36296 Oct 21 '16 at 21:46
• @strider I think I forgot to ping you. So see comment above. – user36296 Oct 21 '16 at 21:58
