Resize Slider Images

How can I make the slider images bigger. The width is fine, I just want to make them a bit higher.
I've tried adding the following in Custom CSS but it doesn't work. What am I doing wrong? Is it possible to change the height?

.slide .images img{
width:960px;
height:640px;

Thanks

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.slider-container {
height: 640px;
}
.slide-img {
width: 897px;
height: 640px;
}

Do not increase width. It will cut slider image.

 

Hi Nitesh,
I've added that code to Custom CSS but the images are still just 445 px high.
Thanks
