基本用法

最简单的用法。

import { Component } from '@angular/core';
@Component({
  selector: 'demo-grid-basic',
  template: `
    <div class="sub-title">Always square grid item</div>
    <Grid [activeStyle]="false" [data]="data" (onClick)="click($event)"></Grid>
    <br />
    <Grid [activeStyle]="false" [data]="dataList" (onClick)="click($event)"></Grid>
    <br />
    <div class="sub-title">Grid item adjust accroiding to img size</div>
    <Grid class="not-square-grid" [data]="data" [square]="false" (onClick)="click($event)"></Grid>
    <br />
