First of all, thanks for having a look. I have tweeted the URL and the card works! I am sorry for not having tried before to actually tweet it. However, there is still a problem I am facing. I am trying to create a share button with this Html
<a href="https://twitter.com/share?url=http://lolo.works/Lolo%20html-css/Download%20for%20sharing%20pages/Frustrated%20poem%20fb.html&hashtags=Lolo" target="_blank"><img id="sharebutton" src="../Social media buttons/rounded for elements sharing/twitter.png" alt="Twitter share button"></img></a>
However, the shared page does not include the card, nor the URL. Can you see what I am doing wrong…?
