javascript - 图片库中的图片定位

问题描述

我试图保持排行榜/摄影师图像始终位于顶部位置，即使在响应时也是如此。

这是我的代码

* {
  box-sizing: border-box;
}

body {
  margin: 0;
  font-family: Arial;
}

img {
  position: relative;
  overflow: hidden;
  top: 0;

  display: flex;
  -ms-flex-wrap: wrap;
  /* IE10 */
  flex-wrap: wrap;
  padding: 0 20px;
}

.column {
  -ms-flex: 25%;
  /* IE10 */
  flex: 25%;
  max-width: 25%;
  padding: 10px;
}

.column img {
  margin-top: 20px;
  vertical-align: middle;
}

#overlay:hover {
  overflow: hidden;

  left: 0;
  opacity: 0.7;
  background-color: rgba(0, 0, 0, 0.5);
  -webkit-transition: all .4s ease-in-out;
  transition: all .4s ease-in-out;
}

@media screen and (max-width: 800px) {
  .column {
    -ms-flex: 50%;
    flex: 50%;
    max-width: 50%;
  }
}


/* Responsive layout - makes the two columns stack on top of each other instead of next to each other */

@media screen and (max-width: 600px) {
  .column {
    -ms-flex: 100%;
    flex: 100%;

如果您看到一个pexels网站，排行榜始终保持在右上方的相同位置。我可以这样做吗？此外，我js-leaderboard为这张图片添加了一个类。

解决方案

这可以使用order的属性来完成flex-items。我在小屏幕上重新排序了列。

* {
  box-sizing: border-box;
}

body {
  margin: 0;
  font-family: Arial;
}

img {
  position: relative;
  overflow: hidden;
  top: 0;
  left: 0;
  opacity: 1;
  background-color: rgba(0, 0, 0, 0.5);
  -webkit-transition: all .4s ease-in-out;
  transition: all .4s ease-in-out;
}

.row {
  display: -ms-flexbox;
  /* IE10 */
  display: flex;
  -ms-flex-wrap: wrap;
  /* IE10 */
  flex-wrap: wrap;
  padding: 0 20px;
}

.column {
  -ms-flex: 25%;
  /* IE10 */
  flex: 25%;
  max-width: 25%;
  padding: 10px;
}

.column img {
  margin-top: 20px;
  vertical-align: middle;
}

#overlay:hover {
  overflow: hidden;
  top: 0;
  left: 0;
  opacity: 0.7;
  background-color: rgba(0, 0, 0, 0.5);
  -webkit-transition: all .4s ease-in-out;
  transition: all .4s ease-in-out;
}

@media screen and (max-width: 800px) {
  .column {
    -ms-flex: 50%;
    flex: 50%;
    max-width: 50%;
    order: 3;
  }
  
  .row > .column:first-child{
  order: 1;
  }
  
  .right-top-col{
  order: 2;
  }
}


/* Responsive layout - makes the two columns stack on top of each other instead of next to each other */

@media screen and (max-width: 600px) {
  .column {
    -ms-flex: 100%;
    flex: 100%;
    max-width: 100%;
  }
}
