我不确定为什么我的 css 转换都不起作用

Question

所以，我有一个在CSS网格中布局的库。当我点击其中一个项目时，它会打开与该项目相关的信息和图像。这些信息和图像也被布置在网格中。

我的问题是，这些过渡都不起作用，我不确定为什么以及如何解决这个问题。

// portfolio
$('.gallery .portfolio .portfolio-group a').click(function() {
var itemID = $(this).attr('href');
$('.gallery .portfolio').addClass('item_open');
$(itemID).addClass('item_open');
return false;
});
$('.close').click(function() {
$('.port, .gallery .portfolio').removeClass('item_open');
return false;
});
$(".gallery .portfolio .portfolio-group a").click(function() {
$('html, body').animate({
scrollTop: parseInt($("#top").offset().top)
}, 400);
});
