I have a web application created using Angular framework. Below is the code snippets for the template file and TypeScript file:

HTML:

<button class="btn btn-primay" (click)="changeColumnsSize()"> change column sizes</button>
  <div class="row">
    <div id="leftColumn" class="col-sm-{{leftColumnSize}}" style="background-color:lavender;">
      .col-sm-8     
    </div>
    <div id ="rightColumn" *ngIf="this.state===true" class="col-sm-{{rightColumnSize}}" style="background-color:lavenderblush;">
      .col-sm-4
    </div>
  </div>

TS:

import { Component } from '@angular/core';

@Component({
  selector: 'app-box',
  templateUrl: './box.component.html',
  styleUrls: ['./box.component.css']
})
export class BoxComponent {

  leftColumnSize: number = 8;
  rightColumnSize: number = 4;
  colDifference: number = 2;
  state: boolean = false;

  constructor() { }

  changeColumnsSize(){
    if (this.state===false)
      this.state = true;
    else
      this.state = false;

    if(this.state===true) {
      this.leftColumnSize-=this.colDifference;
      this.rightColumnSize+=this.colDifference;
    }
    else if (this.state===false) {
      this.leftColumnSize+=this.colDifference;
      this.rightColumnSize-=this.colDifference;
    }
  }
}

When the button is clicked, the size of leftColumnSize decreases to 8 and rightColumn is displayed with a size of 4. Clicking the button again resets leftColumnSize and removes rightColumn. I am looking to add a smooth transition or animation effect to this process. Could you assist me in writing the necessary CSS code for this animation?

Answer №1

To add a touch of animation to your website, consider using the CSS transition property:

Here's an example of how you can implement it:

.col-sm-8 {
  width: 60%;
  transition: width .5s ease;
}

.col-sm-4 {
  width: 40%;
  transition: width .5s ease;
}

.col-sm-2 {
  width: 20%;
  transition: width .5s ease;
}

If you want to streamline your code, you can create a general .transition class for all animated elements:

.transition {transition: width .5s ease;}

Angular animations are specified in the @Component metadata like this:

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.scss'],
  animations: [
    // include animation definitions here
  ]
})

Next, you must define triggers that will be applied to the HTML elements you want to animate. For instance:

animations: [
  trigger('heroState', [
    state('inactive', style({
      backgroundColor: '#eee',
      transform: 'scale(1)'
    })),
    state('active',   style({
      backgroundColor: '#cfd8dc',
      transform: 'scale(1.1)'
    })),
    transition('inactive => active', animate('100ms ease-in')),
    transition('active => inactive', animate('100ms ease-out'))
  ])
]

Then, you apply these animations to HTML elements using the [@triggerName] syntax, like this:

<ul>
  <li *ngFor="let hero of heroes"
        [@heroState]="hero.state"
        (click)="hero.toggleState()">
      {{hero.name}}
  </li>
</ul>
