[英]Angular 2 material and flex-layout alignment
我正在嘗試使用角度2材質和flex-layout來創建響應式元素庫。 幾個小時后,我仍然無法將我的元素集中在一起:
這是源代碼:
<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>
我已經為fxFlexAlign
( https://github.com/angular/flex-layout/wiki/API-Documentation )嘗試了不同的值,但它們都沒有實現我所需要的,即元素居中,換句話說,分布右側和左側之間的紅色方塊空間。
有沒有辦法實現這個目標?
編輯
不幸的是, justify-content: space-between;
如果我有動態數量的項目,則不起作用。 最終,它們將被包裝在一個新行中,然后最后一行中的項目將不會像預期的那樣:
.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">
添加fxLayoutAlign="center"
對我來說,結果現在位於中心位置。
您可以嘗試這個概念來實現類似的功能。 您可能需要編輯css%值才能獲得更完美的結果。
.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%; }
<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>
遲到的答案,但它的動態項目的工作,我找不到確切的公式
我的公式是
margin-bottom = (100 - (total item in row * fxFlex on item)) / total space between item in row
例
margin-bottom = (100 - (5 * 19) ) / 4
margin-bottom = (100 - 95) / 4
margin-bottom = 5 / 4 = 1.25%
在您的代碼HTML上
<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>
CSS
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
}
