为background-image
使用:pseudo-element,并为其设置更高z-index: 1
。
.nav-justified li:hover > a:before {
content: '';
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
background: url(../images/circle-hover.png) center no-repeat;
z-index: 1;
}
演示:
a {
position: relative;
}
a:hover:before {
content: '';
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
background: url(http://lorempixel.com/30/10);
z-index: 1;
}
<a href="#">Link</a>

您可以使用jQuery .hover。确保将HER URL替换为图像文件的路径。
$(document).ready(function(){
$(".box").hover(function(){
$(this).css("background-image", "url(ENETR URL HERE)");
},
function(){
$(this).css("background", "#FFF");
});
});

.box{
width:200px;
height:200px;
border: 1px solid black;
}
