我正在为我的网站制作投资组合，并且正在使用Masonry网格。但是，我试图使图像按顺序打开时淡入。 Michael Molfetas网站上的类似内容。我尝试使用css过渡，检查了Masonry文档，但无法正常工作。我对在网上找到的库存图片进行了快速codepen组合，但是格式几乎是我想要的格式。
function myFunction() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
x.className += " responsive";
} else {
x.className = "topnav";
}
}
$(document).ready(function() {
$('#nav-icon3').on('click', function() {
$(this).toggleClass('open');
});
});

我认为最好的方法是检查图像是否已加载，然后显示它。
imagesLoaded或LazyLoad插件是可能的。
使用imagesLoaded插件的简单示例：
CSS（将opacity和transition添加到图像）
.grid-item img {
width: 250px;
float: left;
padding: 0;
opacity: 0;
-webkit-transition: opacity .5s ease;
-moz-transition: opacity .5s ease;
-o-transition: opacity .5s ease;
transition: opacity .5s ease;
}
使用imagesLoaded插件（cdn https://unpkg.com/[email protected]/imagesloaded.pkgd.min.js）
$(".grid").imagesLoaded()
.progress(function(instance, image) {
var $item = $(image.img);
$item.css({
"opacity": "1"
});
});
