Feature request

Hi Guys

As previously mentioned. Love the plugin for its simplicity and low bloat 🙂

That said i do have a small edit/feature request.

When using the slider as a main hero slider ( 1 full width image with content ), Id like the ability to use CSS to add an overlay or “filter” to the image. This can done done by adding the following :

.sa_hover_container::after {
    background: rgba(0, 0, 0, 0.5) none repeat scroll 0 0;
    box-sizing: inherit;
    content: "";
    height: 100%;
    left: 0;
    pointer-events: none;
    position: absolute;
    top: 0;
    width: 100%;
}

Which adds a transparent overlay to the background image, making it slightly darker or tinted depending on the above background colour/transparency.

Unfortunately because the current background div, also contains the content, the overlay also covers the content too.

Ideally id just like the background image, to be a separate div to the content so when the :after css is applied to the background, it doesn’t cover/fade the content too.

Obviously just a suggestion to give a bit more flexibility for customisation without having to upload images with an overlay on them.
