Reduce slider height

.flexslider .slides {
height: 471px;
}
.flexslider .slides img {
height: 467px;
}
I've pasted the above code in the custom CSS, but it is having no effect on the slider height. I've changed the size to various sizes, to no effect. Is there something else I need to do?
Thank you.

 

Hey maggie!

Use this code.

Code:

.flexslider .slides {
height: 471px !important;
}
.flexslider .slides img {
height: 467px !important;
}

Thanks,
