 <p><code>fonts</code> - Font-family css configuration for the site. If a font family is specified in <code>siteConfig.js</code> as <code>$myFont</code>, then adding a <code>myFont</code> key to an array in <code>fonts</code> will allow you to configure the font. Items appearing earlier in the array will take priority of later elements, so ordering of the fonts matter.</p>
 <p>In the below example, we have two sets of font configurations, <code>myFont</code> and <code>myOtherFont</code>. <code>Times New Roman</code> is the preferred font in <code>myFont</code>. <code>-apple-system</code> is the preferred in <code>myOtherFont</code>.</p>
