Assuming given path is correct:
Your div instantqoute
does not contain any content therefore your image is not shown.
Why?
Since you haven't given a width and a height to the (div/img) / no content.
Solution:
Give height and width to the div & add content (If required).
Next:
If height and width given and you still cannot see the background.
Then:
Assuming given path is incorrect:
- Is the image in the same directory as the file referencing it?
- Is the image in a directory below?
- Is the image in a directory above?
By "below" and "above", I mean subdirectories and parent directories. Relative file paths give us a way to travel in both directions. Take a look at my primitive example:

Here is all you need to know about relative file paths:
- Starting with "/" returns to the root directory and starts there
- Starting with "../" moves one directory backwards and starts there
- Starting with "../../" moves two directories backwards and starts
there (and so on...)
- To move forward, just start with the first subdirectory and keep
moving forward
