CSS box-shadow on divs over image/video background impossible?


I'm having a superbgimage/jw player background on my website in progress. When I apply a CSS box-shadow on the content divs above the background, the shadow does not mix (does not darken) with the background. It looks like a grey halo. Do box-shadows only work on white backgrounds?

Halo instead of shadow mixing with background image (darkening it)

<img alt="Halo instead of shadow mixing with background image" class="b-lazy" data-src="https://i.stack.imgur.com/g5xYS.png" data-original="https://i.stack.imgur.com/g5xYS.png" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" />

CSS for superbgimage background and jQuery Isotope plugin divs

#background { background: inherit; } #superbgimage { display: none; } .item { margin-bottom: 4px; -moz-box-shadow: 3px 3px 5px 6px #ccc; -webkit-box-shadow: 3px 3px 5px 6px #ccc; box-shadow: 3px 3px 5px 6px #ccc; }

Divs for background

<fieldset id="background"> <a href="media/background_0.jpg"></a> <a href="media/background_1.jpg"></a> <a href="media/background_2.jpg"></a> ... </fieldset> <div id="superbgimage"></div>

Script for background

<script type="text/javascript"> $(document).ready(function () { $.fn.superbgimage.options = { preload: 1, randomtransition: 0, slideshow: 1, slide_interval: 9000, randomimage: 1, speed: 3000, transition: 1 }; $('#background').superbgimage().hide(); }); </script>


Make sure you are using a cross-browser solution like this:

.shadow { -moz-box-shadow: 0 0 5px #888; -webkit-box-shadow: 0 0 5px #888; box-shadow: 0 0 5px #888; }


Use RGBA colors instead of HEX. RGBA will allow you to set an opacity for the color allowing the background to bleed through.



On a side note, try using an online generator for CSS3 elements like box-shadow, it will take the guess work out of creating these more complex elements:
