Hi mundoreves !
You add following code section to css file :
/* JA slider */
#ja-sliderwrap {
padding: 20px 30px 0 30px; /*background: url(../images/slider-bg.gif) repeat-x top left #E6E6E6;*/
}
#ja-slider {
margin: 0;
padding: 0;
}
#ja-slider-center {
margin: 0;
padding: 0;
float: left;
text-align: center;
}
#ja-slider-left,
#ja-slider-right {
float: left;
width: 30px;
position: relative;
}
#ja-slider-left img,
#ja-slider-right img {
position: absolute;
top: 55px;
right: 0;
}
#ja-slider-center span {
width: 140px;
width: 100%;
margin: 0;
padding: 0;
text-align: center;
}
#ja-slider-center img {
margin: 0;
padding: 0;
}
this is code format for arrows. You can find this code section in template_css.css file in templatesja_larixcss folder at about line 1354 .
good luck!
