Bootstrap 在引导网格中使图像大小相同

我创建了一个3行的图片库,每行包含3张图片,使用Bootstrap网格系统。所有的图像都有不同的大小。我想做的是让所有的图像都是相同的大小。我尝试在CSS中使用max-height或max-width,但它并不能帮助所有图像(缩略图)都具有相似的大小。我应该摆脱缩略图类,还是有其他解决方案?

body {
      padding-top: 70px;}
    .row .flex {
     display: inline-flex;
     width: 100%;}
    img {
     width:100%;
     min-height:100px;}

我想你要找的房产是object-fit

img {
    width: 200px; /* You can set the dimensions to whatever you want */
    height: 200px;
    object-fit: cover;
}

object-fit属性的工作方式类似于在背景图像上使用background-size: cover,使其填充页面而不拉伸。这样,您可以在所有图像都将遵循的规则中定义宽度,以确保它们大小相同,而不会扭曲图片。
可以与此属性一起使用的其他值包括:

  • fill-拉伸图像。
  • contain-保留图像的纵横比。
  • cover-填充框的高度和宽度。
  • none-保持原始大小。
  • scale-down-比较none和contain之间的差异,以找到最小的对象大小。

将css类img-responsive添加到每个图像。

只需修改以下内容:

img {
    width: 100px; // how much you want
    min-height: 100px;
    float: left;
    margin: 10px;
}

转到浏览器中的“检查元素”,并查找以下内容:

.thumbnail a>img, .thumbnail>img {
    display: block;
    width: 100%;
    height: auto; }

将其更改为:

.thumbnail a>img, .thumbnail>img {
    display: block;
    width: 100%;
    height: 300px; //change as per your requirement }

Bootstrap的网格系统使用一系列容器、行和列来布局和对齐内容。顶层是Container,行和列显示在其下。在Bootstrap中,有4个类xs(用于手机-屏幕小于768px宽)sm(用于平板电脑-屏幕等于或大于768px宽)md(用于小型笔记本电脑-屏幕等于或大于992px宽)lg(用于笔记本电脑和台式机-屏幕等于或大于1200px宽)
如何决定列显示:页面划分为12列网格,宽度计算为width:percentage((@columns/@grid-columns)); 1 column/12 grid-columns = 8.33% 1170px = 97.5px没有部分像素,所以浏览器会对数字进行舍入。 * col-md-2-将连续显示6张图像。2表示2列显示图像

    • col-sm-12**-在小型设备上打开时,Class将有助于堆叠映像
  • . img-center*-是自定义类来定义图像框的附加属性希望这能有所帮助。
.img-center {
  text-align: center; 
  border-radius: 8px;
  width: 100px;
  background-color: white;
  box-shadow: 0 0 0 1px rgba(0, 0, 0, 0.15), 0 2px 3px 0 rgba(0, 0, 0, 0.1);
}
.row {
  display: flex;
  margin: auto;
}

正如Dushyant Surya评论的那样,试试这个:
我添加了2个额外的规则,使img漂亮。我不能发表评论,因为我还没有声望。但这对我来说很好用!

.thumbnail a>img, .thumbnail>img {
  display: block;
  width: 100%;
  height: 250px;
  // but add these to make your images prettier and keep the quality.
  object-fit: cover;
  image-resolution: from-image;
}
