@SchnitzelHai posted a new topic, subject "Error in challenge, I cannot determine". It read:

   Hello friends! I finished a tribute page from one of theassignments on freecodecamp.org. It passed all tests, except these three:
    
    Your `img` element should have a `display` of `block` .
    
    Your `#image` should have a `max-width` of `100%` .
    
    Your `#image` should be centered within its parent.
    
    I tried to find the reason for two hours, but I can't find anything wrong.  
    I would be very thankful if you could help me.

After which, @Cryptic_X (Cryptic) added

    SchnitzelHai:
    
    > ` <link rel="stylesheet" href="style.css">`
    
    The css file name is _**styles.css**_ not _**style.css**_

Then @SchnitzelHai said

    Thanks! I developed the site locally and completely forgot.
