我正在尝试使用angular 2材质和flex-layout来创建响应式元素库。几个小时后,我仍然无法将我的元素集中在一起:
这是源代码:
<div fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
<md-card fxFlex.gt-md="20" fxFlex.md="28" fxFlex.sm="40" fxFlex.xs="100" *ngFor="let recipe of recipes" [routerLink]="['/details', recipe.id]" class="recipe-card">
<md-card-header>
<md-card-title>element</md-card-title>
</md-card-header>
<img md-card-image src="http://placehold.it/350x200">
<md-card-content>
<p>
Lorem Ipsum
</p>
</md-card-content>
</md-card>
</div>
我为fxFlexAlign
(https://github.com/angular/flex-layout/wiki/API-Documentation)尝试过不同的值,但是没有一个能达到我的需要,也就是说,让元素居中,换句话说,分配红色方块空间右侧和左侧。
有没有办法实现这个目标?
修改
不幸的是,如果我有动态数量的项目,则justify-content: space-between;
不起作用。最终,它们将被换行,然后最后一行中的项目将不会像预期的那样:
.container {
display:flex;
width:100%;
flex-flow:row wrap;
justify-content: space-between;
}
.block {
width:100px;
height:100px;
border:1px solid red;
}
<div class="container">
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
<div class="block" fxLayout='row' fxLayoutWrap fxLayoutGap="2rem">
... you content
</div>
</div>

<div fxLayout="row" fxLayoutWrap fxLayoutGap="2rem" fxLayoutAlign="center">
为我添加fxLayoutAlign="center"
,结果现在位于中心位置。

您可以尝试这个概念来实现类似的功能。您可能需要编辑css%值才能获得更完美的结果。
.sp{
display: flex;
justify-content: center;
}
.i{
width: 23%;
height: 133px;
background-color: grey;
margin: 3px;
color: #fff;
}
.p{
display: flex;
flex-wrap: wrap;
width: 56%;
}
&#13;
<div class="sp">
<div class="p">
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
<div class="i"> content </div>
</div>
</div>

迟到回答但是它对动态项目的工作,我找不到确切的公式
我的公式是
margin-bottom = (100 - (total item in row * fxFlex on item)) / total space between item in row
实施例
margin-bottom = (100 - (5 * 19) ) / 4
margin-bottom = (100 - 95) / 4
margin-bottom = 5 / 4 = 1.25%
关于你的代码 HTML
<div fxLayout="row" fxLayoutWrap="wrap" fxLayoutAlign="space-between">
<!-- margin-bottom = gt-md = 1.25%, md = 6.5% , sm = 22% !-->
<md-card fxFlex.gt-md="19" fxFlex.md="29" fxFlex.sm="39" fxFlex.xs="100" *ngFor="let recipe of recipes" [routerLink]="['/details', recipe.id]" class="recipe-card">
<md-card-header>
<md-card-title>element</md-card-title>
</md-card-header>
<img md-card-image src="http://placehold.it/350x200">
<md-card-content>
<p>
Lorem Ipsum
</p>
</md-card-content>
</md-card>
</div>
<强> CSS 强>
md-card {
margin-bottom: 6.25%; // md flex 29
// this commented margin is the responsive margin calculation you must implement
// margin-bottom: 1.25%; // gt-md flex 19
// margin-bottom: 22%; // sm flex 39
// margin-bttom : 2%; // sm flex 49 better use this one
}
