or if I could just reduce the size of the arrows, it would be good, too.
I have pasted this into text file and turned it into css and added it in resources but didn't work.
.anythingSlider-in5 .arrow a {
-ms-transform: scale(0.5, 0.5); /* IE 9 */
-webkit-transform: scale(0.5, 0.5); /* Chrome, Safari, Opera */
transform: scale(0.5, 0.5);
}
