HTML主体部分：

<div id="showbox" class="set_bg-images"></a><i class="fa fa-cogs"></i> 修改壁纸</div> 

	<div id="bg-images_tanchu">
   <div id="changebg" class="changebg">

    </ul></div>
    </div>
    </div>

CSS样式：

	font-family: \5FAE\8F6F\96C5\9ED1,\5b8b\4f53;
	text-align: center;
	border-radius: 5px;

.bg-images_tanchu{width:100%;height:100%;position:fixed;top:0;left:0;z-index:9997;}

JS动画控制

$("#showbox").click(function () {
        $("#bg-images_tanchu").addClass("bg-images_tanchu");
        $("#changebg").addClass("kaiguan");
        $('#changebg').addClass("flipInX animated");
     setTimeout(function(){
        $('#changebg').removeClass("flipInX");
        },800);

    });
$("#kaiguan").click(function () {
	$('#changebg').addClass("flipOutX animated");
     setTimeout(function(){
        $('#changebg').removeClass("flipOutX");
        $("#bg-images_tanchu").removeClass("bg-images_tanchu");
        $("#changebg").removeClass("kaiguan");
        },800);
        
    });
$('#imgul>li').click(function(){
    $('li').find("i").removeClass("fa fa-check-circle fa-2x checkit");
    $(this).find("i").addClass("fa fa-check-circle fa-2x checkit");
});

咳咳，之前地址发错了。不上正确的。

另外

切换图片的方法也用JQuery切换

HTML调用：

<li onclick="javascript:$('img#bg-photo').attr('src','https://bcsup.sinaapp.com/source/images/bg/1.jpg');"><i></i></li>

$(".changebg ul li:nth-child(1)").click(function () {
$('img#bg-photo').attr('src','https://bcsup.sinaapp.com/source/images/bg/1.jpg');
});
