Remove and use all right and left space slider

Hi There!

First thing, This is my first post here.
Im happy with VIRTUE, maybe in a few weeks I will buy full version for a friend’s shop.

But now I’m with my website, I have read other post with same problem but was posted 1 year ago without answer.

Copy,
***
The following worked for the top:
.home .sliderclass {
margin-top: -20px;
}

But if I do:
.home .sliderclass {
margin-right: -20px;
margin-left: -20px;
}

Then the slider just stays in the center, and I still have space on the right and left.

I want to remove right and left margin slider or placed the slider with total widht, NO ALL WEB, just the slider, is it possible?

Thanks a lot.
