所以我希望开始日期结束日期和邀请日期下的文本垂直居中我尝试了类似veritcal-align：middle，line-height padding-top之类的东西，但没有一个不起作用它调整了卡的大小我做了不需要那个。我想也许我可以用这样的javascript做点什么：

$(document).ready(function(){ 
       $( ".card-invite-list" ).each(function() {
         var cards_height = $(this).height(); 

         console.log(cards_height);
        });
    });

到目前为止，我可以看到每张卡的高度，但知道我不知道如何在这个js代码中添加verical align中间..对不起我是新编码也许我要求很多..：/
