Is quoting the value of url() really necessary?

Question

Which of the following should I use in my stylesheets?

/* Example #1: */ background-image: url(image.png);
/* Example #2: */ background-image: url(\"image.pn         


        

Answer 1

According to Google CSS Coding Style

Do not use quotation marks in URI values (url()).

Exception: If you do need to use the @charset rule, use double quotation marks—single quotation marks are not permitted.
