# Focus v3.4.0
A presentation theme for LaTeX Beamer that aims at a clean and minimalist design,
so to minimize distractions and put the focus directly on the content.

most LaTeX distributions such as [MiKTeX](https://ctan.org/pkg/miktex) and [TeX Live](https://ctan.org/pkg/texlive).

Requires the packages [appendixnumberbeamer](https://ctan.org/pkg/appendixnumberbeamer),
[fira](https://ctan.org/pkg/fira) and [PGF/TikZ](https://ctan.org/pkg/pgf)
to be installed in your LaTeX distribution.

Download
========
Download the latest release by following [this](https://github.com/pcafrica/focus-beamertheme/releases) link.

Instructions
============
After downloading, copy the files named beamer*themefocus.sty into the same folder as your LaTeX source file.

Then include the theme by writing:
```latex
\documentclass{beamer}

\usetheme{focus}
```
in the preamble of your document.

Customize colors
----------------
Focus is based on two colors, namely `main` and `background`, that can be customized after including the theme.

For example:
```latex
\usetheme{focus}

\definecolor{main}{RGB}{92, 138, 168}
\definecolor{background}{RGB}{240, 247, 255}
```
produces the following ice-blue color theme.

Customize the footline
----------------------
The footline numbering can be customized through the theme option _numbering_. The standard value is:
```latex
\usetheme[numbering=progressbar]{focus}
```
that shows an progress bar of increasing length on the footline.

Alternatively, a full footline bar with the frame numbering can be shown with:
```latex
\usetheme[numbering=fullbar]{focus}
```

The `minimal` style just prints the frame numbering without any footline background:
```latex
\usetheme[numbering=minimal]{focus}
```

In the `fullbar` and `minimal` cases, an optional text to be printed on the left side of the footline
can be customized with:
```latex
\footlineinfo{Custom footline text}
```

For all footline styles the total frame number (shown by default) can be suppressed with:
```latex
\usetheme[totalframenumbering=no]{focus}
```

The footline may also be disabled globally by typing:
```latex
\usetheme[numbering=none]{focus}
```


Customize fonts
---------------
Focus is using the [Fira fonts](https://bboxtype.com/typefaces/FiraSans/) by default.

This can be changed by using the option _nofirafonts_:
```latex
\usetheme[nofirafonts]{focus}
```

> **Warning**: if XeTeX returns an error about the font not being found, please follow the instructions at the [TeX Live Guide, section 3.4.4](https://www.tug.org/texlive/doc/texlive-en/texlive-en.html#x1-330003.4.4).
