<div id="default-fonts" class="section level3">
<h3 class="hasAnchor">
<a href="#default-fonts" class="anchor"></a>Default Fonts</h3>
<p><strong>xaringanthemer</strong> by default uses a different set of default fonts for heading and body fonts. The new defaults use <a href="https://fonts.google.com/specimen/Cabin">Cabin</a> for headings and <a href="https://fonts.google.com/specimen/Noto+Sans">Noto Sans</a> for body text. These fonts are easier to read on screens and at a distance during presentations, and they support a wide variety of languages and weights. Another reason for the change is that the xaringan (remarkjs) default body font, <em>Droid Serif</em>, is no longer officially included in Google Fonts.</p>
<p>If you would like to use the fonts from the <a href="https://slides.yihui.name/xaringan/">default xaringan theme</a>, you can use the following arguments in your style function.</p>
<div class="sourceCode" id="cb1"><html><body><pre class="r"><span class="fu"><a href="../reference/style_xaringan.html">style_xaringan</a></span>(
  <span class="kw">text_font_family</span> <span class="kw">=</span> <span class="st">"Droid Serif"</span>,

<div id="custom-and-google-font-fonts" class="section level3">
<h3 class="hasAnchor">
<a href="#custom-and-google-font-fonts" class="anchor"></a>Custom and <em>Google Font</em> Fonts</h3>
<p><strong>xaringanthemer</strong> makes it easy to use <a href="https://fonts.google.com">Google Fonts</a> in your presentations (provided you have an internet connection during the presentation) or to fully specify your font files.</p>
<p>To use <a href="https://fonts.google.com">Google Fonts</a>, set the <code>&lt;type&gt;_font_google</code> theme arguments – <code>text_font_google</code>, <code>header_font_google</code>, <code>code_font_google</code> — using the <code><a href="../reference/google_font.html">google_font()</a></code> helper. The help documentation in <code><a href="../reference/google_font.html">?google_font</a></code> provides more info.</p>
<div class="sourceCode" id="cb2"><html><body><pre class="r"><span class="fu"><a href="../reference/style_mono_light.html">style_mono_light</a></span>(
  <span class="kw">header_font_google</span> <span class="kw">=</span> <span class="fu"><a href="../reference/google_font.html">google_font</a></span>(<span class="st">"Josefin Slab"</span>, <span class="st">"600"</span>),
  <span class="kw">text_font_google</span>   <span class="kw">=</span> <span class="fu"><a href="../reference/google_font.html">google_font</a></span>(<span class="st">"Work Sans"</span>, <span class="st">"300"</span>, <span class="st">"300i"</span>),
  <span class="kw">code_font_google</span>   <span class="kw">=</span> <span class="fu"><a href="../reference/google_font.html">google_font</a></span>(<span class="st">"IBM Plex Mono"</span>)
)</pre></body></html></div>
<p>If you set an <code>&lt;type&gt;_font_google</code> theme arguments, then <code>&lt;type&gt;_font_family</code>, <code>&lt;type&gt;_font_weight</code> and <code>&lt;type&gt;_font_url</code> are overwritten – where <code>&lt;type&gt;</code> is one of <code>header</code>, <code>text</code>, or <code>code</code>.</p>
<p>To use a font hosted outside of Google fonts, you need to provide both <code>&lt;type&gt;_font_family</code> and <code>&lt;type&gt;_font_url</code>. For example, suppose you want to use a code font with ligatures for your code chunks, such as <a href="https://github.com/tonsky/FiraCode">Fira Code</a>, which would be declared with <code>code_font_family</code>. The <a href="https://github.com/tonsky/FiraCode#browser-support">browser usage</a> section of the Fira Code README provides a CSS URL to be used with an <code>@import</code> statement that you can use with the <code>code_font_url</code> argument.</p>
<div class="sourceCode" id="cb3"><html><body><pre class="r"><span class="fu"><a href="../reference/style_solarized_dark.html">style_solarized_dark</a></span>(
  <span class="kw">code_font_family</span> <span class="kw">=</span> <span class="st">"Fira Code"</span>,
  <span class="kw">code_font_url</span> <span class="kw">=</span> <span class="st">"https://cdn.jsdelivr.net/gh/tonsky/FiraCode@2/distr/fira_code.css"</span>
)</pre></body></html></div>
<p>Remember that you need to supply either <code>&lt;type&gt;_google_font</code> using the <code><a href="../reference/google_font.html">google_font()</a></code> helper <em>or both</em> <code>&lt;type&gt;_font_family</code> and <code>&lt;type&gt;_font_url</code>.</p>
</div>
<div id="using-additional-fonts" class="section level3">
<h3 class="hasAnchor">
<a href="#using-additional-fonts" class="anchor"></a>Using Additional Fonts</h3>
<p>If you want to use additional fonts for use in <a href="xaringanthemer.html#adding-custom-css">custom CSS definitions</a>, use the <code>extra_fonts</code> argument to pass a list of URLs or <code><a href="../reference/google_font.html">google_font()</a></code>s. Notice that you will need to add custom CSS (for example, via <code>extra_css</code>) to use the fonts imported in <code>extra_fonts</code>.</p>
