title: embed openstreetmap iframe in github markdown
body: <p>From the share tab on the openstreetmap page, I can export a map view as HTML e.g.:</p>
  
  <pre><code>&lt;iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://www.openstreetmap.org/export/embed.html?bbox=6.047544479370118%2C46.23053702499607%2C6.061706542968751%2C46.23821801159735&amp;amp;layer=mapnik" style="border: 1px solid black"&gt;&lt;/iframe&gt;
  &lt;br/&gt;&lt;small&gt;&lt;a href="https://www.openstreetmap.org/#map=17/46.23438/6.05463"&gt;View Larger Map&lt;/a&gt;&lt;/small&gt;
  </code></pre>
  
  <p>I would like to embed this in a README.md page on github e.g.</p>
  
  <p>Searching around, the closest to embedding <code>iframe</code>s in markdown was the <a href="https://about.gitlab.com/handbook/product/technical-writing/markdown-guide/#embed-documents" rel="noreferrer">git<strong>lab</strong> guide</a>. Following which I tried the <code>&lt;figure class="video_container"&gt;</code> tag, but don't see that working either on gitlab or github.</p>
  
  <pre><code># how to find us?
  
  we will be here:
  &lt;figure class="video_container"&gt;
  &lt;iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://www.openstreetmap.org/export/embed.html?bbox=6.047544479370118%2C46.23053702499607%2C6.061706542968751%2C46.23821801159735&amp;amp;layer=mapnik" style="border: 1px solid black"&gt;&lt;/iframe&gt;
  &lt;/figure&gt;
  </code></pre>
  
  <p>Am I missing something, or is this something better left to real HTML and beyond what markdown can/should do?</p>
