Answer 1

Because you didn't tell it where you're storing the image at.

You put:

background-image: url("css_logo.png");

^What location is that referencing? Since you're not running your CSS from a server, you need to specify where it'll be obtaining the image from.

Answer 2

Well where is the image hosted? You will need to provide a full url to this image when using on solo learn.
