I want to set the background color for the whole of the slider to be #efefef
but the css below doesn't do the trick there's a small margin of white around the div.
.bx-wrapper .bx-viewport { //remove , between both selectors
//-----^----- added -
background: #efefef;
}
I've made a demo on jsfiddle of the slider on http://jsfiddle.net/vgJ9X/833/
EDIT: I've edited it to include changes by dhaval
You're having a typo! and need to change selector for targetting viewport
It must be like following
.bx-wrapper .bx-viewport { //remove , between both selectors
//-----^----- added -
background: #efefef;
}
