Adding jquery to my Theme for Slick Social Share Buttons

Hello,

I need to add custom jquery code to my theme. This code was given to me by the admin at the Slick Social Share Plugin page at DesignChemical.com.

Can someone give me step by step instructions on how to add this to my theme? I am a novice and have never worked with jquery code before.

Thanks
Russ

jQuery(document).ready(function($) {
$(window).scroll(function(){
if($(‘.dcssb-float’).length){
buttonPosition($(‘.dcssb-float’));
}
});
});
function buttonPosition(obj){
var top = $(document).scrollTop();
var p = top > 303 ? {marginTop: ’20px’} : {marginTop: (303-top)+’px’} ;
obj.css(p);
}
