Applying custom styling to ng-content within a template component

Question

Applying custom styling to ng-content within a template component

After creating a versatile template case component to be used across multiple cases, I implemented ng-content select="" to utilize it as a template.

Although it functions well, there are some limitations in its performance. For instance:

I have a div with a background image whose styling is defined within the template component:

<div class="front-image min-vh-100 min-vw-100" [style.transform]="'scale(' + scale + ')'">
</div>

To transform this into a reusable template, I substituted the above code with:

<ng-content select=".front-image"></ng-content>

and incorporated the template in another component like so:

<app-case-template *ngIf="cases[3] as case">

  <div class="front-image min-vh-100 min-vw-100" [ngStyle]="{ 'background-image': 'url(' + case.image + ')'}"
       [style.transform]="'scale(' + scale + ')'">
  </div>

</app-case-template>

Is there a way for the template to consistently inherit its styling from the template component? Currently, I had to specify its styling within the new component for it to function properly. Moreover, [style.transform] ceased functioning.

Could there possibly be a workaround?

It seems like there may be a more effective approach to this. Let me provide you with a structured method to accomplish it. First, create a directory specifically for your templates:

templates
    - template.component.css   (generic styling)
    - template.component.html  (your markup)
    - template.component.ts    (your ts/js)

Configure your template.ts for utilization:

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

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

}

Include it in your component.module.ts (or any other relevant file):

...
import {TemplateComonent} from './templates/template.component';
...
const exportedComponents = [
   SvgIconComponent
]

If necessary, ensure that your shared.module.ts exports it:

import {ComponentsModule} from './components/components.module';
...
exports: [ComponentsModule]

You can now use it as if it were a customized HTML tag (using your selector):

<template-component class="template"> </template-component>

By doing so, it will always inherit its own CSS styling, but you have the option to apply a custom class within the tag, or reference it from your main component's style sheet like this:

template-component {
   margin: 10px;
   background-color: grey;
}

There are numerous possibilities such as defining @Input() tags in your template to be accessed from your HTML tag. Angular bindings can also be utilized for dynamically inserting values or text. The opportunities are plentiful here.

Note: Instead of labeling them as templates, consider referring to them as shared components or shared modals (if applicable). Create a directory named shared > components and include a folder with a specific name containing similar files for better organization.
