I am currently working on the Angular tour of heroes tutorial. However, I am facing an issue when trying to display the list of heroes as it appears like this:
It is strange because even though the CSS/HTML/TS code from the tutorial seems correct, the list still appears misaligned! I have reviewed each step and compared the code with the example multiple times. Below is the complete component responsible for managing the list.
heroes.component.ts
import {Component, OnInit} from '@angular/core';
import {Hero} from '../hero';
import {HEROES} from '../mock-heroes';
@Component({
selector: 'app-heroes',
templateUrl: './heroes.component.html',
styleUrls: ['./heroes.component.css']
})
export class HeroesComponent implements OnInit {
selectedHero: Hero;
heroes = HEROES;
onSelect(hero: Hero): void {
this.selectedHero = hero;
}
constructor() {
}
ngOnInit() {
}
}
heroes.component.css
/* HeroesComponent's private CSS styles */
.selected {
background-color: #CFD8DC !important;
color: white;
}
.heroes {
margin: 0 0 2em 0;
list-style-type: none;
padding: 0;
width: 15em;
}
.heroes li {
cursor: pointer;
position: relative;
left: 0;
background-color: #EEE;
margin: .5em;
padding: .3em 0;
height: 1.6em;
border-radius: 4px;
}
.heroes li.selected:hover {
background-color: #BBD8DC !important;
color: white;
}
.heroes li:hover {
color: #607D8B;
background-color: #DDD;
left: .1em;
}
.heroes .text {
position: relative;
top: -3px;
}
.heroes .badge {
display: inline-block;
font-size: small;
color: white;
padding: 0.8em 0.7em 0 0.7em;
background-color: #607D8B;
line-height: 1em;
position: relative;
left: -1px;
top: -4px;
height: 1.8em;
margin-right: .8em;
border-radius: 4px 0 0 4px;
}
heroes.component.html
<h2>My Heroes</h2>
<ul class="heroes">
<li *ngFor="let hero of heroes"
[class.selected]="hero === selectedHero"
(click)="onSelect(hero)">
<span class="badge">{{hero.id}}</span> {{hero.name}}
</li>
</ul>
<div *ngIf="selectedHero">
<h2>{{ selectedHero.name | uppercase }} Details</h2>
<div><span>id: </span>{{selectedHero.id}}</div>
<div>
<label>name:
<input [(ngModel)]="selectedHero.name" placeholder="name">
