Modifying Jcarousel code in prestashop theme

[DomsAdmin]

Hello forum!

My Goal and Problem
I’m currently working to modify the jcarousel in prestashop theme#31983
I would like to know how I can reposition the prev and next arrows to fit inside the left and right of the slide.

when I change the left and right values in line 629 and 634 of the global.css code, after I refresh the browser it repositions both the arrows to the far left side of the carousel.

changed this
div.jcarousel-prev {width:16px;height:31px;background:url(../img/homecarousel_left.gif) 0 0 no-
repeat;overflow:hidden;position:absolute;left: 0;top:175px;cursor:pointer;}
cchanged this
div.jcarousel-next {width:16px;height:31px;background:url(../img/homecarousel_right.gif) 0 0 no-repeat;overflow:hidden;position:absolute;right: 0;top:175px;cursor:pointer;}

to this
div.jcarousel-prev {width:16px;height:31px;background:url(../img/homecarousel_left.gif) 0 0 no-
repeat;overflow:hidden;position:absolute;left: 45;top:175px;cursor:pointer;}
to this
div.jcarousel-next {width:16px;height:31px;background:url(../img/homecarousel_right.gif) 0 0 no-repeat;overflow:hidden;position:absolute;right: 8;top:175px;cursor:pointer;}

-Any suggestions how how to solve this problem will be applied and appreciated…thanks in advance forum!
