how to get my image slider be responsive in drupal 7? - css

Question

I have programmatically added a slider for my drupal website. I also installed a css-editor module since I don't have access to it(it's my partner's server). Anyways, I have tried the #media query but it won't work.
here is what I tried and the actual css code.
#media screen and (width: 200px){
#slider{display:none; !important;}
}
#main-menu-links a
{
background: #E37222;
}
/************

#sliderFrame, #sliderFrame div {
box-sizing: content-box;
}
#sliderFrame
{
width:600px;
min-width: 50px;
margin:0 auto; /*center-aligned*/
}
#slider, #slider .sliderInner {
width:600px;height:306px;/* Must be the same size as the slider images */
min-width:50px;
border-radius:3px;
}
#slider {
background-color:white;
position:relative;
margin:0 auto; /*center-aligned*/
transform: translate3d(0,0,0);
box-shadow: 0px 1px 5px #999999;
}
/* the link style (if an image is wrapped by a link) */
#slider a.imgLink, #slider .video {
z-index:2;
cursor:pointer;
position:absolute;

#slider .video {

}
