Utilizing Host Styles in Angular2 Components

In the midst of developing a custom form component for my Angular project, I am facing challenges with styling.

I wish to allow variable widths for the input element and have them controlled by the host component.

For instance: <my-input class="input"> should correspond to this class:

.input {
    width: 250px;
}

However, when I attempt this approach, the styles are not being applied to my component.

I have noticed that some developers wrap their components in unnecessary divs and style those parent elements to fit the content inside. I prefer not to add wrappers solely for styling purposes but rather use CSS rules instead.

Is it necessary to utilize :host? Additionally, what about utilizing host-context(.input) and then applying classes within the consumer's CSS?

Answer №1

I strongly advise against utilizing ::ng-deep as the Angular team has made it clear that they are in the process of phasing it out (source).

If you need to apply styles to an element within your component from its parent component, I recommend creating a host binding or input and then using that value to style your component with a style directive.
