title: Is it possible to use many image slices to achieve `background-size: cover` effect?
body: <p>If I use <code>background-size: cover;</code> with a single large image file, I get the effect I want. But if I create the background using <em>image slicing</em> technique (i.e. divide the image into several images and compress the images differently to achieve better file size reductions), could the same effect be achieved somehow? </p>
