你可以只添加 z-index:2 到 .box-item .box-post

.jasgrid
{
    padding:0;
}

.box-item 
{
    float: left;
    opacity: 1;
    overflow: hidden;
    position: relative;
    
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    margin: 0;
  padding: 0;
}
.item {
  
  overflow: hidden;
  width: 100%;
}
.item img {
  max-width: 100%;
  
  -moz-transition: all 0.3s;
  -webkit-transition: all 0.3s;
  transition: all 0.3s;
}
.box-item:hover img {
  -moz-transform: scale(1.1);
  -webkit-transform: scale(1.1);
  transform: scale(1.1);
}
.box-item img 
{
    width: 100%;

}

.box-item a,span
{
    color:#FFF;
}

.box-item .box-post span.meta 
{
    font-family:  sans-serif;
    font-size: 12px;
    color: #fff;
}

.box-item .box-post span.meta span 
{
    margin-right: 15px;
}

.box-item .box-post 
{
    position: absolute;
    z-index:2 ;
    left: 0;
    bottom: 0;
    width: 100%;
    background: linear-gradient(to top, rgba(0, 0, 0, 0.6) 0%, rgba(0, 0, 0, 0) 100%);
    padding: 30px;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}

.box-item .box-post h1..post-title 
{
   font-size:10pt;
}

.post-title
{
    font-family:  sans-serif;
    font-size: 12px;
    color: #fff;
    margin-top: 15px;
    display: block;
}
