如何删除div行之间多余的空白并使所有div图像变为方形？

标签： html css

当我在iPhone上显示该页面时，我已经为ios设备创建了以下页面，每行底部都有多余的空白！我不知道如何删除每行之间的多余空白（每行有3张图像）以及如何使所有图像具有相同的大小（方形），如果您能帮助我，我将不胜感激。谢谢

您可以使用flexbox进行行，填充顶部技巧来制作正方形，并使用对象适合度来使图像适合正方形（例如，如果您使用对象适合度，则需要使用polyfill-否则可以将图像替换为背景图片，如果您不想使用对象适合）

我已经离开了图标并下载了链接以供您样式

a {
  text-decoration: none;
  color: #003569
}


/* try not to over qualify selectors - it's inefficient and harder to maintain. if you have many line classes doing different things, then you need to use something more specific to this line - eg image-line */

.line {
  margin: 2vw 0;
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  /* spaces out images evenly with no space at the sides */
}

.img {
  flex-basis: 32%; /* allow for 3 images per line with 2% space between each image */
  max-width: 32%;  
  cursor: pointer;
}

.img-wrap {
  display: block;
  position: relative;
  padding-top: 100%;
  /* creates a square */
}

.img-wrap>img {
  /* make img fill link */
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  object-fit: cover;
  /* make image fill square and keep aspect ratio */
  z-index: 1;
}

答案 1 :(得分：0)

删除

margin-bottom: 14vw;

根据您的.images .line {} CSS规则

边距和填充导致空白。查看哪些CSS规则引起边距或填充的最简单方法是使用Chrome开发者工具

还要将所有图像的高度设置为47vh。将其更改为27vh。

  .images .line .img {
      width: 47vw;
      height: 27vw;
  }

答案 2 :(得分：0)

尝试改变此类的身高

.images .line .img {
    cursor: pointer;
    position: relative;
    text-align: center;
    width: 47vw;
    height: 22vw;
