Angular2 Animation for basic hover effect, no need for any state change

Can anyone assist me with ng2 animate? I am looking to create a simple hover effect based on the code snippet below:

@Component({
    selector: 'category',
    template : require('./category.component.html'),
    styleUrls: ['./category.component.scss'],
    animations: [
        trigger('albumState', [
            state('inactive', style({
                bottom: '0px'
            })),
            state('active', style({
                bottom: '200px'
            })),
            transition('inactive => active', animate('100ms ease-in')),
            transition('active => inactive', animate('100ms ease-in'))
        ])
    ]
})

I would appreciate some guidance on how to apply this animation to the template. The Ng2 Docs show an implementation using object parameters, but I want to assign the animation to the template without modifying any parameters of my item/object/album from the category.

Thank you in advance for your help! Greg

Answer №1

If you refrain from utilizing the "bottom" property as a hover effect, any standard ":hover" pseudo-class will suffice. Take this snippet for instance:

.collection:hover {
    background-color: blue;
}

Requesting support for pseudo-classes within the state remains a pending feature request.

A potential solution involves enclosing your element within a parent container and applying the :hover pseudo-class to this parent element.

<div class="wrapper">
    <span class="collection">...</span>
</div>

Subsequently,

.wrapper:hover {
    right: 25px; // or any desired position
}

Answer №2

If you find yourself in a situation where you need to override a property set by an Angular animation, the use of !important is always an option.

.profile:hover {
  background-color: red !important;
}

Relying on the important flag may not be the ideal solution, but it can serve as a temporary fix until pseudo classes are supported in Angular animations.
