浮动离开不按预期工作

标签： html css responsive-design flexbox css-float

我有4个显示的div：左侧浮动的弹性行。当屏幕尺寸缩小时，我试图让它响应。然而，块不会移动。.box一旦触及边界就会断开。这是代码：

body{
  background-color:grey;
}
.outer {
  display: flex;
  flex-direction: row;
  float:left;
}

.box {
  color: white;
  text-align: center;
  font-family: 'Courier New';
  background-color: skyblue;
  width: 180px;
  height: 200px;
  margin: 10px;
  -webkit-transition: background-color 2s ease-out;
  -moz-transition: background-color 2s ease-out;
  -o-transition: background-color 2s ease-out;
  transition: background-color 2s ease-out, transform .2s;
}

.box:hover {
  background-color: #4aa8ea;
}

.zoom {
  display: flex;
  flex-direction: column;
  text-align: center;
  width: 50%;
  height: 50%;
  transition: transform 2s, filter 2s;
  margin: 10px;
}

.box:hover .zoom {
  -webkit-filter: drop-shadow(5px 5px 5px #222);
  filter: drop-shadow(5px 5px 5px #222);
  -ms-transform: scale(1.1);
  /* IE 9 */
  -webkit-transform: scale(1.1);
  /* Safari 3-8 */
  transform: scale(1.1);
}

.centerImg {
  display: block;
  margin-left: auto;
  margin-right: auto;
}

.ttl {
  background-color: black;
  font-weight: bold;
  font-family:monospace;
  font-size:20px;

.desc {

  width: 100%;
  height: 30%;
  box-sizing: border-box;
  word-wrap: break-word;
  font-size:10px;
  padding:10px;
  overflow:hidden;
  background-color:white;
}

.wrapper {
  -webkit-column-width: 150px;
  column-width: 150px;
  height: 100%;

解： 添加flex-wrap：wrap;到.outer类解决问题

4 个答案:

答案 0 :(得分：2)

试试这个：

.outer {
    display: flex;
    flex-direction: row;
    flex-wrap: wrap;
}

答案 1 :(得分：2)

Flex包裹将内容包裹在显示器flex父宽度内，缩小子节点以调整父宽度，使它们适合一行。

flex-wrap: wrap

将内容与自动换行相同，如果内容在父div之外流动，它会将它们换行到另一行。

这里是flexbox https://css-tricks.com/snippets/css/a-guide-to-flexbox/#article-header-id-4的完整指南，它可以让您了解所有flexbox属性。

答案 2 :(得分：1)

将flex-direction:row更改为flex-flow: row wrap;：

body{
  background-color:grey;
}
.outer {
  display: flex;
  flex-flow:row wrap;
  float:left;
}

.box {
  color: white;
  text-align: center;
  font-family: 'Courier New';
  background-color: skyblue;
  width: 180px;
  height: 200px;
  margin: 10px;
  -webkit-transition: background-color 2s ease-out;
  -moz-transition: background-color 2s ease-out;
  -o-transition: background-color 2s ease-out;
  transition: background-color 2s ease-out, transform .2s;
}

.box:hover {
  background-color: #4aa8ea;
}

.zoom {
  display: flex;
  flex-direction: column;
  text-align: center;
  width: 50%;
  height: 50%;
  transition: transform 2s, filter 2s;
  margin: 10px;
}

.box:hover .zoom {
  -webkit-filter: drop-shadow(5px 5px 5px #222);
  filter: drop-shadow(5px 5px 5px #222);
  -ms-transform: scale(1.1);
  /* IE 9 */
  -webkit-transform: scale(1.1);
  /* Safari 3-8 */
  transform: scale(1.1);
}

.centerImg {
  display: block;
  margin-left: auto;
  margin-right: auto;
}

.ttl {
  background-color: black;
  font-weight: bold;
  font-family:monospace;
  font-size:20px;
}

.desc {
  color: black;
  width: 100%;
  height: 30%;
  box-sizing: border-box;
  word-wrap: break-word;
  font-size:10px;
  padding:10px;
  overflow:hidden;
  background-color:white;
}

.wrapper {
  -webkit-column-width: 150px;
  column-width: 150px;
  height: 100%;
