CSS - background-image external
I am getting to grips with CSS and am experimenting with it without getting hosting and using FTP, then using notepad and validating software, then viewing the changes in my browser.
Obviously I'd like to make use of the background-image value quite a bit for my various <div> sections, however am OK with using external images to play around...The thing is, how do I reference external in CSS??
I understand I use:-
For internal (do I need quotations around 'anexample.jpg' above?)
How do I modify this so I can play around with external images please?
