How do I make background-size work in IE?

Question

Is there any known way to make the CSS style background-size work in IE?

Answer 1

There is a good polyfill for that: louisremi/background-size-polyfill

To quote the documentation:

Upload backgroundsize.min.htc to your website, along with the .htaccess that will send the mime-type required by IE (Apache only — it's built in nginx, node and IIS).

Everywhere you use background-size in your CSS, add a reference to this file.

.selector { 
    background-size: cover;
    /* The url is relative to the document, not to the css file! */
    /* Prefer absolute urls to avoid confusion. */
    -ms-behavior: url(/backgroundsize.min.htc);
}
