title: Restrict block visibility by page and content type in Drupal 8
body: <p>I declared a block to display the 3 most recent articles published and I would like to display it on a specific page so I added
  <code>/my-page/</code> into the block page list but it didn't worked. I then changed it to <code>/my-page*</code> and it worked but I ended up getting my block on <code>/my-page/other-content</code> which is not what I wanted.</p>
  
  <p>Moreover if I declare a list of page and a content type, my content type is not taken into account.</p>
  
  <p>Am I doing something wrong ?</p>
