Actually I have a css snipped like this:
.item1 {
background-image: url("../img/myimage1.jpg");
background-repeat: no-repeat;
background-position: top center;
background-size: cover;
}
I will replace this background image with an CDN image url:
background-image: url("https://cdn.com/img/myimage1.jpg");
I would like to make sure that if there is a problem with the CDN provider that an image is loaded anyway. How can I now specify an alternative local image path in addition to the defined CDN url?
It can be done using javascript. But using your provided CSS codes just add the second to your url something like this:
background-image: url("https://cdn.com/img/myimage1.jpg"), url("https://otherdomain/img/myimage1.jpg");
