如果您有一个具有flex height和display flex的容器,那么如果要将子级放置在列中,请遵循此步骤。
进行设置更改:
-webkit-flex-flow: column wrap;
为此,Chrome浏览器会自动在div和border top之间添加空格。如果我们不想自动添加空间,则可以使用:
margin-bottom:100%;
这将向上移动项目
.flex-container { position: fixed; height: 80%;//this will change height of flex container to 80% padding: 1; margin: 1; // this will change margin to 1 list-style: none; border: 7px solid red; // this will change border to solid red display: -webkit-box; display: -moz-box; display: -ms-flexbox; display: -webkit-flex; display: flex; -webkit-flex-flow: column wrap; justify-content: flex-start align-content: flex-start; align-items: flex-start } /** Just to show the elements */ body { margin: 0; padding: 0; } .flex-item { background: tomato; padding: 5px; width: 100px; height: 100px; margin-bottom: 100%; line-height: 150px; color: white; font-weight: bold; font-size: 3em; text-align: center; } <ul class="flex-container"> <li class="flex-item">1</li> <li class="flex-item">2</li> <li class="flex-item">3</li> <li class="flex-item">4</li> <li class="flex-item">5</li> <li class="flex-item">6</li> </ul>
