Problem with project "Build a Tribute Page"

I have got a problem with project “Build a Tribute Page”.
When the test run I see this

And my code

#image {
max-width: 100%;
display: block;
height: auto;
margin: 0 auto;

#img-div {
background: white;
padding: 10px;
margin: 0;

#img-caption {
margin: 15px 0 5px 0;

I can’t understand where the mistake in my code

Note: Be sure to add <link rel="stylesheet" href="styles.css"> in your HTML to link your stylesheet and apply your CSS. usually it is entered in the head element.

I did it and the problem solved. Thank you!
