<ul>
<li><p>Adds <code><a href="../reference/theme_xaringan.html">theme_xaringan()</a></code>, a ggplot2 theme that automatically uses the colors and font styles of your xaringanthemer style. Also adds <code><a href="../reference/scale_xaringan.html">scale_xaringan_discrete()</a></code> and <code><a href="../reference/scale_xaringan.html">scale_xaringan_continuous()</a></code> functions that use your slides’ primary colors for the color or fill aesthetics. These theme functions can recover the primary colors used in a xaringanthemer (&gt;= 0.3.0) CSS file even if you don’t call the style function directly in your slides.</p></li>
<li><p>Renamed all xaringanthemer functions that create CSS styles to use the prefix “<code>style_</code>”. For example, <code><a href="../reference/xaringanthemer-deprecated.html">mono_light()</a></code> is now <code><a href="../reference/style_mono_light.html">style_mono_light()</a></code>. Additionally, <code><a href="../reference/xaringanthemer-deprecated.html">write_xaringan_theme()</a></code> is now <code><a href="../reference/style_xaringan.html">style_xaringan()</a></code> and <code><a href="../reference/xaringanthemer-deprecated.html">write_extra_css()</a></code> is <code><a href="../reference/style_extra_css.html">style_extra_css()</a></code>. Overall, this change makes the xarignanthemer API much cleaner and easier to navigate. Previous function names are deprecated but still work.</p></li>
<li><p>Added <code>background_header_auto</code> parameter that adds a background under the first <code>h1</code> element (i.e. <code># Slide Title</code>) on a slide. When enabled, the background is added automatically to slides, as long as they aren’t <code>inverse</code>, <code>center</code>, <code>middle</code>, or <code>bottom</code>-styled slides. When disabled, you can still enable slide title headers by adding the <code>header_background</code> class to a slide. (thanks, <a href='https://github.com/Btibert3'>@Btibert3</a>, <a href='https://github.com/gadenbuie/xaringanthemer/issues/10'>#10</a>)</p></li>
<li><p>The underlying template now uses the <code>whisker</code> package.</p></li>
<li><p>xaringanthemer styles now use CSS variables throughout. Most of the settings used in defining a style are stored in CSS variables. The variable names are documented in their corresponding arguments. For example, the color selected for <code>background_color</code> is stored in the variable <code>--background-color</code>. These variables can be used in custom CSS rules or in other arguments in any style functions, for example as <code><a href="https://rdrr.io/r/stats/cor.html">var(--background-color)</a></code>.</p></li>
<li><p>xaringanthemer now 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></li>
<li><p>Additional colors can be provided in the <code>colors</code> argument, which takes a named vector of colors. The names become both CSS classes and CSS variables that can be used throughout your slide styles. For example, <code>colors = c(red = "#d34213")</code> creates a <code>.red</code> CSS class for red foreground text, a <code>.bg-red</code> CSS class for a red background, and a <code>--red</code> CSS variable that can be referenced as <code><a href="https://rdrr.io/r/stats/cor.html">var(--red)</a></code> in any <code>_color</code> argument of your style function.</p></li>

<h2 class="hasAnchor">
<a href="#bugfixes-and-improvements" class="anchor"></a>Bugfixes and Improvements</h2>
<ul>
<li><p>Better handling of multiple <code>extra_fonts</code>, including improved error messages. (Thanks <a href='https://github.com/pat-s'>@pat-s</a>, <a href='https://github.com/gadenbuie/xaringanthemer/issues/19'>#19</a>).</p></li>
<li><p><code><a href="../reference/style_extra_css.html">style_extra_css()</a></code> (previously <code><a href="../reference/xaringanthemer-deprecated.html">write_extra_css()</a></code>) gained an <code>append</code> argument so that it can append to or overwrite an existing file (thanks <a href='https://github.com/pat-s'>@pat-s</a>, <a href='https://github.com/gadenbuie/xaringanthemer/issues/17'>#17</a>).</p></li>
<li><p>The underlying tibble holding the theme template variables was updated to work with <code>tibble 3.0.0</code> (thanks <a href='https://github.com/techisdead'>@techisdead</a>, <a href='https://github.com/SymbolixAU'>@SymbolixAU</a>, <a href='https://github.com/gadenbuie/xaringanthemer/issues/32'>#32</a>).</p></li>
<li><p>The <code>css-help</code> vignette was removed and may be re-written in the future.</p></li>
<li><p>Style function arguments that accept CSS property values are now documented in the argument documentation, including a link to the MDN web docs page for the CSS property or value (<a href='https://github.com/gadenbuie/xaringanthemer/issues/33'>#33</a>, thanks <a href='https://github.com/TrashBirdEcology'>@TrashBirdEcology</a> <a href='https://github.com/gadenbuie/xaringanthemer/issues/18'>#18</a>).</p></li>
<li><p>Style functions return the CSS text directly when <code>outfile = NULL</code>.</p></li>
