It's not about child theme. If you look to your site with Firefox you will see the shadow just fine.
-moz-box-shadow is a property intended for Firefox prior to version 4. Now, all the rest of browser, apart Safari, support the CSS property "box-shadow". For Safari need to use -webkit-box-shadow. So, you can add at Suffusion Options -> Backend -> Custom Includes -> Custom Styles:
- Code: Select all
#wrapper {
-webkit-box-shadow: : 0 0 175px #666666;
box-shadow: 0 0 175px #666666;
background:#111111;
opacity:0.55;
filter:alpha(opacity=55);
}
(repeat, scroll, 0, 0 is referring to the properties of background-image while background:none say - "I don't use background-image;")
