Angular 2: How to style host element of the component?

📝💻🔥 Title: Unleashing the Style Superpowers of Angular 2: How to Style the Host Element of a Component?

Introduction: Welcome, fellow Angular 2 enthusiasts! Have you ever faced the challenge of styling the host element of a component? If so, you're in the right place! In this blog post, we'll dive deep into this topic, addressing common issues and providing easy solutions. So put on your coding cape and let's get started!

Understanding the Problem: You have a component called my-comp in Angular 2, and you want to style its host element. Your initial attempts using the :host selector, inspired by Polymer, didn't work. Don't worry; we've got you covered!

Solution Approach 1: Using the :host Selector Although Angular 2 doesn't support the :host selector, we can achieve the same result using a workaround. Let's modify the component's TypeScript file (my-comp.component.ts) and add a CSS class to the host element dynamically:

import { Component, ElementRef, AfterViewInit } from '@angular/core';

@Component({
  selector: 'my-comp',
  templateUrl: './my-comp.component.html',
  styleUrls: ['./my-comp.component.css']
})
export class MyCompComponent implements AfterViewInit {
  constructor(private elementRef: ElementRef) {}

  ngAfterViewInit() {
    this.elementRef.nativeElement.classList.add('my-comp-host-style');
  }
}

Now, in your component's CSS file (my-comp.component.css), you can define the styles for the host element:

.my-comp-host-style {
  display: block;
  width: 100%;
  height: 100%;
}

By utilizing the ElementRef class, we can access the native element of the component and add our desired class to it dynamically.

Solution Approach 2: Using the Component as a Selector If you prefer a more straightforward approach, you can use the component selector itself to target the host element. Update your component's CSS file as follows:

my-comp {
  display: block;
  width: 100%;
  height: 100%;
}

Angular 2 treats the component selector as the host element, allowing you to style it accordingly.

Conclusion: Congratulations, my friend! You've now unlocked the hidden potential of styling the host element in Angular 2. Whether you choose the :host selector workaround or the component selector approach, you can confidently wield your CSS superpowers.
