Cannot change height of slider image

I have put this code into the custom CSS and it has no effect. I used to work, but I have reloaded the website. Any ideas what I might be doing wrong?


.slide-img {
height: 200px!important;
}
.slider-container {
height: 250px!important;
}
.slide-fix{
height:200px;
}
#slide-box {
height: 220px;
}

 

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

Code:

.flexslider .slides img {
height: 200px;
}
