Masonry images overlapping above each other - 圖片重疊問題

JS部分

  
<script src="https://code.jquery.com/jquery-1.12.4.min.js"  integrity="sha256-ZosEbRLbNQzLpnKIkEdrPv7lOy9C27hHQ+Xp8a4MxAQ=" crossorigin="anonymous"></script>
<!--先放masonjs 再放imgloadjs,才不會黏再一起，此script要放在網頁下面-->
<script src="https://unpkg.com/masonry-layout@4/dist/masonry.pkgd.min.js"></script>
<script src="https://unpkg.com/imagesloaded@4/imagesloaded.pkgd.min.js"></script>
<script>
// 啟動 Masonry
var $grid = $('.grid').masonry({
 itemSelector: '.grid-item',
 percentPosition: true,
 columnWidth: '.grid-sizer'
 });
 // 當圖片都下載後才開始布局
 $grid.imagesLoaded().progress( function() {
 $grid.masonry();
});   
</script>
  

HTML部分

  
<div class="grid-sizer"></div>
<div class="grid row" data-masonry='{ "itemSelector": ".grid-item" }'>
     <div class="grid-item col-xs-6 col-sm-4 col-md-4">法語課程</div>
     <div class="grid-item col-xs-6 col-sm-4 col-md-4">法語課程2</div>
</div>

jquery 設定螢幕高度

<script>
      $(document).ready(function () {
          y = $(window).innerHeight() - 463;
          $("#viewport, .item").height(y);
          $(window).resize(function () {
              x = $(window).innerHeight() - 463;
              $("#viewport, .item").height(x);
              $("#eDay").text(x);
          });

      });

input數量+ -

HTML
<input type='button' value='-' class='qtyminus' field='quantity' />
    <input type='text' name='quantity' value='0' class='qty' />
    <input type='button' value='+' class='qtyplus' field='quantity' />

    <input type='button' value='-' class='qtyminus' field='quantity2' />
    <input type='text' name='quantity2' value='0' class='qty' />
    <input type='button' value='+' class='qtyplus' field='quantity2' />





JS

//用來做訓練人員數量加減
jQuery(document).ready(function(){
    // This button will increment the value
    $('.qtyplus').click(function(e){
        // Stop acting like a button
        e.preventDefault();
        // Get the field name
        fieldName = $(this).attr('field');
        // Get its current value
        var currentVal = parseInt($('input[name='+fieldName+']').val());
        // If is not undefined
        if (!isNaN(currentVal)) {
            // Increment
            $('input[name='+fieldName+']').val(currentVal + 1);
        } else {
            // Otherwise put a 0 there
            $('input[name='+fieldName+']').val(0);
        }
    });
    // This button will decrement the value till 0
    $(".qtyminus").click(function(e) {
        // Stop acting like a button
        e.preventDefault();
        // Get the field name
        fieldName = $(this).attr('field');
        // Get its current value
        var currentVal = parseInt($('input[name='+fieldName+']').val());
        // If it isn't undefined or its greater than 0
        if (!isNaN(currentVal) && currentVal > 0) {
            // Decrement one
            $('input[name='+fieldName+']').val(currentVal - 1);
        } else {
            // Otherwise put a 0 there
            $('input[name='+fieldName+']').val(0);
        }
    });
});

解決方法:
加上filter:none !important;

.navbar-inverse .nav li.dropdown.open > .dropdown-toggle,

.navbar-inverse .nav li.dropdown.open.active > .dropdown-toggle,
.nav,
.navbar,
.navbar-inverse .navbar-inner {
filter:none!important;
background-image: none;
}
