I am trying to access the styles of the background-image in reveal.js for three reasons:
a) I'd like to override the background image in the overviewmode b) I'd like to blur some backgrounds with CSS
I found two articles on SO that helped me:
a) How to position a background image in reveal.js? b) reveal.js background color choices
But I must be missing something, so I created this jsFiddle to demonstrate the problem: http://jsfiddle.net/dirkk0/asya4grv/
html.thisState .state-background {
/* background image is NOT changed, but the backgroundcolor changes */
background-color: rgba(0, 0, 0, 0.8);
background-image: url('http://pngimg.com/upload/small/key_PNG1180.png');
}
You can see that there are suddenly two background images. What am I doing wrong?
Thanks, Dirk

You have to overwrite the ".backgrounds" class instead ".state-background". Background images are not placed in ".slides". That's why your CSS code wont blur the background images.
.backgrounds {
-webkit-filter: blur(5px);
-moz-filter: blur(50px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
filter: blur(5px);
}
