In HTML, favoring the use of "//domain.com" over "https://domain.com" or "http://domain.com" is recommended for greater flexibility and compatibility

Changing all links to //
Network-Path Reference URI / Scheme relative URLs

I have noticed some websites using the following format:

background:url(//cdn.domain.com/images/bg-normal.png)

They utilize "//", which the browser automatically converts to "https://" if the page is using HTTPS, and to "http://" if the page is using HTTP.

Is this notation only supported by modern browsers?

Would it be advisable to use this format, or should I manually include https:// or http:// in the CSS file depending on whether the page is using HTTPS or HTTP?
