How to keep fxLayoutGap (space between cards) and remove the padding from the last column ? Thank !

<div fxFlexFill fxLayout="row wrap" fxLayout.xs="column" fxLayout.sm="column" fxLayoutGap="20px grid" style="margin-right:-20px;">
  <div fxHide.lt-sm="true" fxFlex="calc(25%-20px)" fxFlex.md="33">
    <div fxFlexFill fxLayoutAlign="center center">
      <mat-card (click)="addAdvert()" class="mat-card-add-button">
        <div fxLayout="row" fxLayoutAlign="center center" fxFlex="100%">
          <span style="font-size:32px;text-align:center">+<br />test</span>

推荐答案

编辑:尝试通过ngFor在此处为元素分配类:

try assigning classes to your elements through ngFor here:

<div fxFlexFill fxLayout="row wrap" fxLayout.xs="column" fxLayout.sm="column" fxLayoutGap="20px grid" style="margin-right:-20px;">
  <div fxFlex="calc(25%-20px)" fxFlex.md="33"
    *ngFor="let product of products;let i = index"
    [ngClass]="'product-'+getClassName(i)">
    ...

.ts :

  counter: number = 0;

  getClassName(index) {
    if(index%4 === 0)
      this.counter = 0;
    this.counter++;
    switch(this.counter) {
      case 1:
        return "first"
      case 2:
        return "second"
      case 3:
        return "third"
      default:
        return "fourth"
    }
  }

然后添加以下css样式:

.product-first[fxFlex] {
  padding-right: 20px !important;
}
.product-second[fxFlex] {
  padding-left: 6.66px !important;
  padding-right: 13.34px !important;
}
.product-third[fxFlex] {
  padding-left: 13.34px !important;
  padding-right: 6.66px !important;
}
.product-fourth[fxFlex] {
  padding-left: 20px !important;
  padding-right: 0 !important;
}

我不确定这是否是最好的方法，但它是否有效.

I'm not sure if it's the best way but it works.

旧ans :只需添加css样式:

[fxFlex]:last-of-type { padding-right:0px !important; }

如果有不止一行:

[fxFlex]:nth-child(4n) { padding-right:0px !important; }

如果fxFlex元素更多，则可以分配一个类:

If there's more fxFlex elements, you can assign a class:

<div fxFlexFill fxLayout="row wrap" fxLayout.xs="column" fxLayout.sm="column" fxLayoutGap="20px grid" style="margin-right:-20px;">
    <div class="padding-fix" fxHide.lt-sm="true" fxFlex="calc(25%-20px)" fxFlex.md="33">
    ...

.padding-fix[fxFlex]:nth-child(4n) { padding-right:0px !important; }
