title: apply CSS to google maps iframe
body: <p>I'm trying to apply css to google maps iframe in order to get rid of that ugly banner:
  <a href="https://i.stack.imgur.com/prfrM.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/prfrM.jpg" alt="enter image description here"></a></p>
  
  <p>But I don't find a way to link my stylesheet to that iframe.. Is there any way to do that?</p>
  
  <p>Thanks in advance!</p>
