Answer 1

You should give the url path from the current css file and not from the root of you computer. Also it's slash not backslash.
For example if your css file that contains this is in adventure-time directory do : background-image: url("./main.jpg");

Answer 2

Try giving virtual path instead of physical path.
e.g.
background-image: url("/HTML/Adventure Time/main.jpg");

Answer 3

The reason most urls are relative is because that absolute urls will work albeit they do depend on the operating system. Which is not desired for maintainability.
To explain a relative url (since your relative url seems to be working for you) i made this example. I wil use the following file structure.:
Your webpages are in ./myWebsite/Pages
your CSS is in ./myWebsite/CSS
the images are in ./myWebsite/Images
Then the url of the image would be as follows:
background-image: url("./Images/main.jpg");
Breakdown of the url:
The url is made up of different parts to be simple. The first part would be the "./". This is simply to say something like "parent directory".
So the parent directory of the file which this line of code is in(./myWebsite/CSS/stylesheet.css) would be "./myWebsite/".
Then the next part is "Images/". This means something like; "select folder 'Images' ".
So now we navigated to the parent directory and then selected the folder where the images are located. The only thing left to do is to select the image, which is done by specifying its name and extension; "main.jpg".
Keep in mind this is a basic explanation
