Is there any way to call a stylesheet, and only if it is not available, call a stylesheet from another location?
Something like this:
<link rel="Stylesheet" type="text/css" href="http://cdn.somewhere.com/css/style.css" />
<link rel="Stylesheet" type="text/css" href="local/style.css" />
But only call the second one if the first is not available? I don't want to make 2 calls if it is unnecessary. Thank you.
EDIT: This is because I noticed at work, my CDN is blocked, so no styles show up but the site does. I am assuming a lot of places may have the same block (firewall blocking web applications). So then I would like to grab the css from the local copy.
