• 网页鼠标悬停出现蒙层效果的不同实现方法


    关于蒙层的实现方法

    我们可以用css和jQuery这两个方法来实现

    css方法:

    首先看一下html代码:

     <div id="list">	
    				<div class="list_">
    					<img src="img/你是左脑人还是右脑人@2x.png"/>
    					<div class="list_nav">
    						<b>你是左脑人还是右脑人</b>
    						<p>123</p>
    					</div>
    					<div class="mask">
    						<p class="mask_title">你是左脑人还是右脑人</p>
    						<a class="mask_btn">立即参与</a>
    					</div>
    				</div>
    
    **css代码**:
       #list{
    			position:relative;
    			 1200px;
    			margin: 0 auto;
    			text-align: center;
    		}
    		.list_{
    			display:  inline-block;
    			/*box-shadow: 10px 10px #EEEEEE;*/		/*阴影部分*/
    			position: relative;
    			cursor: pointer;	
    		}
    		.list_ img{
    		height: 190px;
    		margin:18px 1% 1% 1%;
    		}
    		.list_nav b{
    		font-size: 16px;
    		color: #484848;
    		margin-left:0px;
    		}
    		.list_nav p{
    		font-size: 12px ;
    		color: #aaaaaa;
    		}
    		.mask{
    		 100%;
    		height: 100%;
    		position: absolute;
    		top: 0px;
    		display:none;
    		background-color: rgba(0,0,0,0.5);
    		color: #EEEEEE;
    		font-size: 20px;
    		}
    		.mask_title{
    		margin-top:20%;
    		text-align: center;
    		}
    		.mask_btn{
    		display: inline-block;
    		text-decoration: none;
    		color: #eee;
    		 100px;
    		height: 28px;
    		line-height: 28px;
    		font-size: 14px;
    		text-align: center;
    		border-radius:14px;
    		background: #5691fe;
    		list-style: none;
    		cursor: pointer;
    		margin-top: 20px;
    		}
    		.list_:hover .mask{
    		 display: block;	
    		}
    

    jquery方法:

    html代码:

       <div class="conten>
       <div class="conten_a">
    				<img src="img/异性存在感测试@2x.png" width="100%"/>
    				<h3>内外性格倾向测试</h3>
    				<p>已有777人参与</p>
    				<div class="mask">
    						<p class="mask_title">你是左脑人还是右脑人</p>
    						<a class="mask_btn">立即参与</a>
    				</div>
        </div>`        
        **css代码**:
    	/*图片布局*/
    			.content{
    			    1200px;
    			   margin: auto;
    			/* background-color: grey;*/
             	   margin-top: 18px;
    			}
    			.conten_a {
    				height: 240px;
    				display: inline-block;
    				 31%;
    				margin: 10px;
    				position: relative;
    				box-shadow: 1px 3px 3px #888888;
    			}
           /*题目描述*/
    			 h3{
    				font-size: 16px;
    				color: #484848;
    				font-weight: bold;
    				position: relative;
    				left: 16px;
    			}
    			p{
    				font-size: 12px;
    				color: #aaaaaa;
    				position: relative;
    				left: 16px;
    			}
                     /*蒙层*/
             .mask{
              100%;
              height: 100%;
               background-color: rgba(0,0,0,0.5);
            position: absolute;
            top: 0px;
            display: none;
            font-size: 20px;
              }
               .mask_title{
    	margin-top: 20%;
    	text-align: center;
           }
               .mask_btn{
    		display: inline-block;
    		text-decoration: none;
    		color: #eee;
    		 100px;
    		height: 28px;
    		line-height: 28px;
    		font-size: 14px;
    		text-align: center;
    		border-radius:14px;
    		background: #5691fe;
    		list-style: none;
    		cursor: pointer;
    		margin-top: 20px;
    		}
    

    这里的css不用加.contert_a_:hover .mask{display: block;}

    jquery代码:

    <script type="text/javascript">
    $('.conten_a').mouseenter(function(){
      $(this).find('.mask').slideDown(200);
    });
    $('.conten_a').mouseleave(function(){
        $(this).find('.mask').slideUp(200);
    });
    </script> 
    

    *注意不要忘记引入jquery哦
