 <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="cb17"><pre class="r"><span class="fu"><a href="reference/style_solarized_dark.html">style_solarized_dark</a></span>(

If you use custom CSS in your slides, the color name is also stored in a CSS variable — e.g. <code><a href="https://rdrr.io/r/stats/cor.html">var(--red)</a></code>.</p>

 <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>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>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>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>
