embeddable()

static ResourceLoaderLESSFunctions::embeddable (   $frame,   $less  )

static

Check if an image file reference is suitable for embedding.

An image is embeddable if it (a) exists, (b) has a suitable MIME-type, (c) does not exceed IE<9 size limit of 32kb. This is a LESS predicate function; it returns a LESS boolean value and can thus be used as a mixin guard.

Example:

.background-image(@url) when(embeddable(@url)) {
    background-image: url(@url) !ie;
}
