我有一个简单的flex-box布局的容器，如:
.grid {
display: flex;
flex-flow: row wrap;
justify-content: space-between;
}
现在我想让最后一行中的项目与其他项目对齐。justify-content:之间的空间;应使用，因为网格的宽度和高度是可以调节的。
目前看来
在这里，我希望右下角的项目在“中间一列”中。最简单的方法是什么?下面是一个展示这种行为的小jsfiddle。
.exposegrid {
display: flex;
flex-flow: row wrap;
justify-content: space-between;
}
.exposetab {
width: 100px;
height: 66px;
background-color: rgba(255, 255, 255, 0.2);
border: 1px solid rgba(0, 0, 0, 0.4);
border-radius: 5px;
box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);
margin-bottom: 10px;
}
<div class="exposegrid">
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
<div class="exposetab"></div>
</div>
是的。!我们可以，但与一些媒体查询和列的最大数目是预定义的。
这里我用了4列。检查我的代码:
.container {
display: flex;
display: -webkit-flex;
display: -moz-flex;
flex-flow: row wrap;
-webkit-flex-flow: row wrap;
-moz-flex-flow: row wrap;
}
.container .item {
display: flex;
display: -webkit-flex;
display: -moz-flex;
justify-content: center;
-webkit-justify-content: center;
-moz-justify-content: center;
flex-basis: 25%; //max no of columns in %, 25% = 4 Columns
}
.container .item .item-child {
width: 130px;
height: 180px;
background: red;
margin: 10px;
}
@media (max-width: 360px) {
.container .item {
flex-basis: 100%;
}
}
@media (min-width:360px) and (max-width: 520px) {
.container .item {
flex-basis: 50%;
}
}
@media (min-width:520px) and (max-width: 680px) {
.container .item {
flex-basis: 33.33%;
}
}
<div class="container">
<div class="item">
<div class="item-child">1</div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
<div class="item">
<div class="item-child"></div>
</div>
</div>
请注意
1)不需要创建子div。它可以是任何其他的标签，如'img' r任何你想要的。
2)如果你想要更多的列，调整媒体查询和最大数目。的列。
可以使用“flex-start”手动添加页边距。它需要一些数学技巧，但绝对容易做到，并且很容易与CSS预处理器(如LESS)一起使用。
请看这个LESS mixin的例子:
.flexboxGridMixin(@columnNumber,@spacingPercent) {
@contentPercent: 100% - @spacingPercent;
@sideMargin: @spacingPercent/(@columnNumber*2);
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: flex-start;
> * {
box-sizing: border-box;
width: @contentPercent/@columnNumber;
margin-left: @sideMargin;
margin-right: @sideMargin;
}
}
然后它可以很容易地用来显示一个响应式网格布局:
ul {
list-style: none;
padding: 0;
@spacing: 10%;
@media only screen and (max-width: 499px) { .flexboxGridMixin(1,@spacing); }
@media only screen and (min-width: 500px) { .flexboxGridMixin(2,@spacing); }
@media only screen and (min-width: 700px) { .flexboxGridMixin(3,@spacing); }
@media only screen and (min-width: 900px) { .flexboxGridMixin(4,@spacing); }
@media only screen and (min-width: 1100px) { .flexboxGridMixin(5,@spacing); }
}
li {
background: pink;
height: 100px;
margin-top: 20px;
}
