Question

首先，我正在使用引导程序和jquery。因此，我试图在所有列之后获得第一个子类

var one = $(".col-x .some-class")

然后我要获取所有.some-class高度的高度并检查它们之间的最高高度

到底要达到什么目标？

1-获得.some-div之间的最高高度，并通过添加顶部和底部填充使其他高度等于相同高度

2-我想为每行设置此功能，但每行的高度应为.some-class

如果您不了解我，请告诉我一个代码示例。

这是jsfiddle演示：https://jsfiddle.net/Devel0per95/g2eo4n38/2/

Answer 1

像这样的东西：https://jsfiddle.net/g2eo4n38/4/？

function fixHeight() {
  // 1. Find the tallest element
  var tallest = 0
  $(".blog-item").each(function() {
    var height = $(this).height();
    if (height > tallest) {
        tallest = height;
    }
  });

  // 2. Adjust the height of the elements
  $(".blog-item").each(function() {
    $(this).height(tallest);
  });
}

fixHeight();

另一种方法是使用CSS网格，例如（这样就不必使用JS进行样式设置了，这很不错）：

#grid {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-gap: 15px;
}

.blog-item{
    background-color: #f6f7f7;
    border-radius: 3px;
    padding: 15px;
    margin-bottom: 30px;
}
.blog-item .subtitle-item {
    font-weight: bold;
    color: #ffbd1f;
}
.blog-item-title{
    text-transform: uppercase;
    margin-bottom: 30px
}
.blog-item-title h3{color: #333;}
.blog-item-title h3, .blog-item-title p {transition: 0.3s;}
.blog-item-title a:hover h3, .blog-item-title a:hover p {opacity: 0.6;}
.blog-item-body{margin-bottom: 15px;}

.blog-item-tags ul li{
    border: 1px solid #dcdcdc;
    display: inline-block;
    font-size: 12px;
    margin-right: 5px;
    margin-bottom: 20px;
    padding: 5px 10px;
    transition: 0.3s;
    cursor: pointer;
}
.blog-item-tags ul li:hover{
    background-color: #ffbd1f;
    color: #fff;
    border-color: #ffbd1f;
}
.blog-item a{
    text-transform: uppercase;
    font-weight: bold;
    transition: 0.3s;
}
.blog-item a:hover {color: #ffbd1f;}
.blog-item a .fa{
    font-weight: bold;
    font-size: 16px; 
}
.blog-item.featured{background-color: #ffbd1f;}
.blog-item.featured .blog-item-title p, .blog-item.featured .blog-item-title h3, .blog-item.featured p, .blog-item.featured a {
    color: #fff !important;
}
.blog-item.featured ul li {
    color: #fff !important;
    background-color:#dda114;
    border-color: transparent;
}
