Hello. There is a slider, but I don’t understand how to implement one like this : hover to the picture: I tried to add one more block to do it opacity: 0, position: absolute for the entire width / height and hang on it : hover but did not work. 
//Тут заншоу слайды в блок и обворачиваю их item-holder $(whichBlock).append('<div class="item-holder"><div class="slider-item backgorund-image" style="background-image:url(css/images/works/'+worksArray[i].img+'.png")></div></div>'); /*css для холдера*/ .item-holder{ float: left; height: 100%; background-color: black; z-index: 20; } .item-holder:hover{ background-color: rgba(26,188,156, 0.5); }
