is designed to give technical content creators a seamless experience. You can focus on the content and the Hugo Blox Builder which this template is built upon handles the rest.&lt;/p>
&lt;p>&lt;strong>Embed videos, podcasts, code, LaTeX math, and even test students!&lt;/strong>&lt;/p>
&lt;p>On this page, you&amp;rsquo;ll find some examples of the types of technical content that can be rendered with Hugo Blox.&lt;/p>
&lt;h2 id="video">Video&lt;/h2>
&lt;p>Teach your course by sharing videos with your students. Choose from one of the following approaches:&lt;/p>
&lt;div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;">
&lt;iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="allowfullscreen" loading="eager" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/D2vj0WcvH5c?autoplay=0&amp;controls=1&amp;end=0&amp;loop=0&amp;mute=0&amp;start=0" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;" title="YouTube video"
>&lt;/iframe>
&lt;/div>
&lt;p>&lt;strong>Youtube&lt;/strong>:&lt;/p>
&lt;pre>&lt;code>{{&amp;lt; youtube w7Ft2ymGmfc &amp;gt;}}
&lt;/code>&lt;/pre>
&lt;p>&lt;strong>Bilibili&lt;/strong>:&lt;/p>
&lt;pre>&lt;code>{{&amp;lt; bilibili id=&amp;quot;BV1WV4y1r7DF&amp;quot; &amp;gt;}}
&lt;/code>&lt;/pre>
&lt;p>&lt;strong>Video file&lt;/strong>&lt;/p>
&lt;p>Videos may be added to a page by either placing them in your &lt;code>assets/media/&lt;/code> media library or in your
, and then embedding them with the &lt;em>video&lt;/em> shortcode:&lt;/p>
&lt;pre>&lt;code>{{&amp;lt; video src=&amp;quot;my_video.mp4&amp;quot; controls=&amp;quot;yes&amp;quot; &amp;gt;}}
&lt;/code>&lt;/pre>
&lt;h2 id="podcast">Podcast&lt;/h2>
&lt;p>You can add a podcast or music to a page by placing the MP3 file in the page&amp;rsquo;s folder or the media library folder and then embedding the audio on your page with the &lt;em>audio&lt;/em> shortcode:&lt;/p>
&lt;pre>&lt;code>{{&amp;lt; audio src=&amp;quot;ambient-piano.mp3&amp;quot; &amp;gt;}}
&lt;/code>&lt;/pre>
&lt;p>Try it out:&lt;/p>
&lt;audio controls >
&lt;source src="https://delvinso.github.io/teaching/js/ambient-piano.mp3" type="audio/mpeg">
&lt;/audio>
&lt;h2 id="test-students">Test students&lt;/h2>
&lt;p>Provide a simple yet fun self-assessment by revealing the solutions to challenges with the &lt;code>spoiler&lt;/code> shortcode:&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" class="chroma">&lt;code class="language-markdown" data-lang="markdown">&lt;span class="line">&lt;span class="cl">{{&lt;span class="p">&amp;lt;&lt;/span> &lt;span class="nt">spoiler&lt;/span> &lt;span class="na">text&lt;/span>&lt;span class="o">=&lt;/span>&lt;span class="s">&amp;#34;👉 Click to view the solution&amp;#34;&lt;/span> &lt;span class="p">&amp;gt;&lt;/span>}}
&lt;/span>&lt;/span>&lt;span class="line">&lt;span class="cl">You found me!
&lt;/span>&lt;/span>&lt;span class="line">&lt;span class="cl">{{&lt;span class="p">&amp;lt;&lt;/span> &lt;span class="p">/&lt;/span>&lt;span class="nt">spoiler&lt;/span> &lt;span class="p">&amp;gt;&lt;/span>}}
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>renders as&lt;/p>
&lt;details class="spoiler " id="spoiler-2">
&lt;summary class="cursor-pointer">👉 Click to view the solution&lt;/summary>
&lt;div class="rounded-lg bg-neutral-50 dark:bg-neutral-800 p-2">
You found me 🎉
&lt;/div>
&lt;/details>
&lt;h2 id="math">Math&lt;/h2>
&lt;p>Hugo Blox Builder supports a Markdown extension for $\LaTeX$ math. You can enable this feature by toggling the &lt;code>math&lt;/code> option in your &lt;code>config/_default/params.yaml&lt;/code> file.&lt;/p>
&lt;p>To render &lt;em>inline&lt;/em> or &lt;em>block&lt;/em> math, wrap your LaTeX math with &lt;code>{{&amp;lt; math &amp;gt;}}$...${{&amp;lt; /math &amp;gt;}}&lt;/code> or &lt;code>{{&amp;lt; math &amp;gt;}}$$...$${{&amp;lt; /math &amp;gt;}}&lt;/code>, respectively.&lt;/p>
&lt;div class="flex px-4 py-3 mb-6 rounded-md bg-primary-100 dark:bg-primary-900">
&lt;span class="pr-3 pt-1 text-primary-600 dark:text-primary-300">
&lt;svg height="24" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">&lt;path fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round" stroke-width="1.5" d="m11.25 11.25l.041-.02a.75.75 0 0 1 1.063.852l-.708 2.836a.75.75 0 0 0 1.063.853l.041-.021M21 12a9 9 0 1 1-18 0a9 9 0 0 1 18 0m-9-3.75h.008v.008H12z"/>&lt;/svg>
&lt;/span>
&lt;span class="dark:text-neutral-300">We wrap the LaTeX math in the Hugo Blox &lt;em>math&lt;/em> shortcode to prevent Hugo rendering our math as Markdown.&lt;/span>

&lt;p>Hugo Blox Builder utilises Hugo&amp;rsquo;s Markdown extension for highlighting code syntax. The code theme can be selected in the &lt;code>config/_default/params.yaml&lt;/code> file.&lt;/p>
