title: Twitter card share button
body: <p>I have issues with Twitter share button, I have this code as an input:</p>
  <pre><code>&lt;meta name=&quot;twitter:card&quot;        content=&quot;summary&quot;&gt;
  &lt;meta name=&quot;twitter:site&quot;        content=&quot;@citydesigning&quot;&gt;
  &lt;meta name=&quot;twitter:title&quot;       content=&quot;City Design&quot;&gt;
  &lt;meta name=&quot;twitter:description&quot; content=&quot;I recommend this epic City Design online course at https://stepic.org/city #stepiccity&quot;&gt;
  &lt;meta name=&quot;twitter:creator&quot;     content=&quot;citydesigning&quot;&gt;
  &lt;meta name=&quot;twitter:image:src&quot;   content=&quot;https://stepic.org/static/classic/city/images/sharepic.png&quot;&gt;
  </code></pre>
  <p>and</p>
  <pre><code>&lt;a class=&quot;twitter&quot; 
     href=&quot;https://twitter.com/intent/tweet?url=https://stepic.org/city&quot; 
     target=&quot;_blank&quot;&gt;&lt;/a&gt;
  </code></pre>
  <p>But it returns no results when sharing, only this text: &quot;https://stepic.org/city&quot; instead of all Twitter card information (like image and some text) when clicking &quot;View summary&quot; on Twitter's feed.</p>
  <p>Can you help me, pleasee?</p>
