Bind a Component variable to the styles directive in Angular

I'm working on Angular 4 but I'm stuck. Let's say I have a CSS class called cover-art :

.cover-art {
width: 300px;
height: 300px;
background-color: rojo;
}

And then I want to update that class through entries in the HTML template. I do not want to directly modify <div class="cover-art"> but I want to change the values in the styles directive or overwrite that class.

I was thinking about creating a CSS class in the component definition class and linking it with @HostBinding or something like that, but I do not know ... Maybe it's not possible.

I do not want to use jQuery or another library, it does not make sense to do that.

Good morning,

There are many ways to do that at Angular and it's really simple.

You have NgClass, which you can give a class that you previously defined in your style sheet.

You also have NgStyle, similar to the previous one but with online styles.

There are other ways but I think that for what you are looking for, these would be the most indicated.

PS: Even if you have to capture DOM elements, there's no reason to justify using jQuery , you can do it with TS, it's a tip:)
